Answer 1

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

Here's the solution ~

$\qquad \sf  \dashrightarrow \: (3 {a}^{2} {b}^{4} )( - 8a {b}^{3} )$

$\qquad \sf  \dashrightarrow \: (3 \times - 8)( {a}^{2} \times a)(b {}^{4} \times {b}^{3} )$

$\qquad \sf  \dashrightarrow \: - 24( {a}^{3} )( {b}^{7} )$

$\qquad \sf  \dashrightarrow \: - 24 {a}^{3} {b}^{7}$

So, The Correct choice is D
