B
Correct Answer
A formal power series ∑ a_n x^n encoding a sequence as coefficients, enabling algebraic manipulation to solve combinatorial problems
Explanation
Generating functions: G(x) = ∑ a_n x^n. Ordinary GF for Fibonacci: F(x) = x/(1-x-x²). Exponential GF: ∑ a_n x^n/n!. Operations on GFs correspond to operations on sequences (convolution, shifting).
