Volume of a rectangular prism is ~

\sf{Volume_{cuboid}= Length × Width × Height}

\qquad \sf  \dashrightarrow \: v = (4x + 2) \times (3x - 5) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = (12 {x}^{2} - 20x + 6x - 10) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = (12 {x}^{2} - 14x- 10) \times (7x + 4)

\qquad \sf  \dashrightarrow \: v = 84 {x}^{3}  + 48 {x}^{2}  - 98x {}^{2}  - 56x - 70x - 40

\qquad \sf  \dashrightarrow \: v = 84 {x}^{3} - 50 {x}^{2}  -  126x - 40

So, the correct choice is B
