Given a geometric sequence (Sn)(S_n) with the parity of first term a1a_1, the parity of the number of terms nn, and the parity (odd or even nature) of the common ratio rr, is it possible to determine the parity of the terms in the sequence (Sn)(S_n)?

APossible
BImpossible, need value of a1a_1
CImpossible, need value of nn
DImpossible, need value of rr
EAll of them are incorrect
