Correct answer
D
Step-by-step explanation
To find the coefficient of term independent of in given expression, first let's find constant term and coefficient of in the expansion of
For constant term: , hence constant term =
For coefficient of , hence coefficient of
Given expression can be written as
Hence, coefficient of term independent of
For constant term: , hence constant term =
For coefficient of , hence coefficient of
Given expression can be written as
Hence, coefficient of term independent of
