B
We have 
Since the limit of the given expression is zero, therefore degree of the polynomial in numerator must be less than that of denominator. As the denominator is a first degree polynomial. So, numerator must be a constant i.e., a zero degree polynomial. ∴ ∴ 
=0 and 
⇒ ⇒ a = 1 and b = –1. Hence, a = 1 and b = – 1.
