Solution

The correct option is A $105 a^{7}$
We know,
Volume of a rectangle= $l e n g t h \times b r e a d t h \times h e i g h t$

Given,
length,breadth, height= $5 a, 3 a^{2}, 7 a^{4}$

Therefore,
Volume of a rectangle= $5 a \times 3 a^{2} \times 7 a^{4}$
= $105 a^{7}$

Hence option $^{'} A^{'}$ is the answer.
