Using Binomial Theorem, we will know that each term will have binomial coefficients nCk (n choose k) for 0 ≤ k ≤ 6

Here, we have n = 6 so coefficients are ₆C₀, ₆C₁, ₆C₂, ₆C₃, ₆C₄, ₆C₅, ₆C₆

Which is same as 1, 6, 15, 20,15, 6, 1, respectively, therefore answer is B.

Another way to solve is to look at 6th row of pascal's triangle.

Answer:

1, 6, 15, 20,15, 6, 1,
