Assertion (A): In an intrinsic semiconductor J = (μ_n x μ_p)en_i. Reason (R): Intrinsic charge concentration n_i at temperature T is given by n_i² = A₀ T³ e^-E_G0/kT.

A Both A and R are true and R is correct explanation of A

B Both A and R are true but R is not correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:B - Both A and R are true but R is not correct explanation of A

It's wrong option.

Because assertion is wrong.

Here hole and electron mobilities are added not multiples.
