If the sum of binomial coefficients in the expansion of (x+y)^{n} is 256, then the <strong>GREATEST</strong> binomial coefficient occurs in which one of the following terms?

Explanation

The sum of binomial coefficients is 2^n = 256, which gives n = 8. For an even n, the greatest binomial coefficient is the middle term, which is the (\frac{n}{2} + 1)-th term. So, \frac{8}{2} + 1 = 5th term.
