Thanks to you BRO... you identified where i mistake.

Yes... If possible number of inputs are $2^n$ then we have n variables and n-1 EXOR gates are needed.

@Shaik sir.  Shouldn't it be $2^n$ inputs means $2^n$ minterms are possible out of which odd parity function will be 1 for $2^{n-1}$ minterms ?

odd parity function will be 1 for 2ⁿ⁻¹ min terms ?

yes mam
