What are the coefficients for the binomial expansion of open paren p plus q close paren to the 6th power ?

For (p + q)^6, the coefficients are the binomial coefficients in row 6 of Pascal’s triangle, found using ⁶C₀ through ⁶C₆. They are 1, 6, 15, 20, 15, 6, 1, so the correct choice is C, “1, 6, 15, 20, 15, 6, 1.”
