If C(0), C(1), ....,C(n) are binomial co...

If `C_(0), C_(1), ....,C_(n)` are binomial coefficients in the expansion of `(1 + x)^(n)`, then `C_(0) + C_(1).(x)/(2) + C_(2).(x^(2))/(3)+-----+C_(n).(x^(n))/(n+1) =`

A

`((1 + x)^(n+1)-1)/((n + 1))`

B

`((1 + x)^(n+1))/((n + 1)x)`

C

`((1 + x)^(n+1)+1)/((n + 1)x)`

D

`((1 + x)^(n+1) + 1)/((n + 1))`
