|---|---|---|---|
| A | Torque vector | I | \( \mathbf{r} \times \mathbf{p} \) |
| B | Angular momentum vector | II | \( \frac{d_2}{d_1} \) |

Correct answer · Option 2
A-(IV), B-(I), C-(II), D-(III)
Explanation
Torque is \( \mathbf{r} \times \mathbf{F} \) (A-IV); Angular momentum is \( \mathbf{r} \times \mathbf{p} \) (B-I); Mechanical advantage is \( d_2/d_1 \) (C-II); Dimensions of torque are \( [M L^2 T^{-2}] \) with unit N·m (D-III).
