Let there be a G.P. whose first term is a and the common ratio is \( r \). If \( A \) and \( H \) are the arithmetic mean and the harmonic mean respectively for the first \( n \) terms of the G.P. Then, AH is equal to
(A) \( a^{2} r^{n-1} \)
(B) \( a r^{n} \)
(C) \( a^{2} r^{n} \)
(D) none of these
