As you know that the speed decreases to 1/n times the speed in air where n is the refractve index of glass w.r.t. air while frequency remains constant.
and as the eqaution V = µ * wavelength holds true in both cases the wavelenth also decreases to 1/n times the wavelength in air.

Maxwell had given maxwell's equation for electrodynamic, where he coined the word displacement current between plates of a capacitor due to variable electric field.

Take help from formula.
As we know that induced emf is given as rate of change of magnetic flux of the coil, so focus on the parameter
(i)rate of change ........... related to option D
(ii)flux of the coil....... related to option A & C
so option B is correct as resistance comes into play when induced current is to be calculated.

Force F is given as cross product of velocity and magnetic field multiplied my charge with sign.
So off course the force will be perpendicular to both V and B. (option D is correct)

As you know that power is P=i^2 * R where R is external resistance (load) and i is current drawn by it .
While i = E /(R+r) where r is internal resistance.
For maximum power R=r so P becomes E^2 /4r
option D may be correct after the correction:- there should be r in denominator alongwith 4 .

Torque is given by PESin ø, where ø is angle between field E and dipole moment P so if angle ø is zero or 180 degree only then torque will be zero while net force will be zero always because both charges will experience equal and opposite force .
opposite as both charges have opposite nature.
same force because same electric field in the region and same magnitude of charge as F=qE; so both q and E to be looked for analysis.
Note- Uniform electric field means same direction and magnitude at any point in the region of uniform field.

As you know that the shear modulus, also known as the modulus of rigidity, is a measure of a material's resistance to shear deformation, and since liquids readily deform under shear stress (i.e. readily changes their shape on application of stress so it can be said that NO resisatance ), so their shear modulus is considered to be zero

Mass
Inertia is related to heaviness or lightness.
Velociy is responsible for momentum while inertia can come into play when body is in rest also.

Two vectors will have their vector sum maximum when they act parallel i.e angle between them is zero, option A here.
For mathematical explanation refer to the formula of parallelogram, it will give that resultant (R) will be maximum when the angle is zero.

As we know that from our text book:-
Work and energy has same dimensions so energy upon volume and work upon volume will have same dimensions while work is force*displacement (W= F*d) so work/volume will have dimension of Force/area as volume has dimension of area*length.
Similarly voltage*charge is nothing but work so volatge*charge/volume will have same dimension as work/volume that is same as that for A & B so A,B and D have same dimensions leading to C as correct answer (different from A, B & D)
