All the terms of the expansion (X + Y + Z + W )30 are of the form k ∗ Xa ∗ Y b ∗ Zc ∗Wd where a,b,c,d are all positive integers
and a+b+c+d=30
We need to find number of solutions of above equation and that will be the number of distinct terms in the expansion
number of solutions of equation a+b+c+d=30 is given by (n + r − 1)Cr−1 here n = 30 and r = 4
therefore number of solutions = (33)C3 = 5456
Therefore our answer is Option 'B'
