a_1, a_2, a_3, \ldots, a_9

are in G.P., then

\left|\begin{array}{lll}\log a_1 & \log a_2 & \log a_3 \\ \log a_4 & \log a_5 & \log a_6 \\ \log a_7 & \log a_8 & \log a_9\end{array}\right|=

View answer and explanation

Correct option: A

Option A (0) is correct because the determinant of the matrix is zero due to the properties of logarithms and arithmetic progressions in a G.P.
