Please answer these question......

Dear student, 
(D) both A and B is correct option.
This is because we know that angle of deviation in prism is given by 
δ=i + e - A
where i is the angle of incidence , A is the angle of prism and given by A = r1 + r, where  these r1 and r2 are angle of refractions inside the prism which will depend on the refractive index of prism and angle of incidence i .

Size of prism is immaterial because when can have large and small prisms with the same A.

Regards
