If \( G \) is the G.M. of the product of \( r \) sets of observations with geometric means \( G_{1}, G_{2}, \ldots, G_{r} \) respectively, then \( G \) is equal to
(A) \( \log G_{1}+\log G_{2}+\ldots+\log G_{n} \)
(B) \( G_{1}, G_{2} \ldots G_{n} \)
(C) \( \log G_{1} \cdot \log G_{2} \ldots \log G_{n} \)
(D) none of these
