1. Let’s think step-by-step.

The relative error in X is defined as the absolute error divided by the measured value

$$\frac{\Delta X}{X} = \frac{\frac{\Delta a}{a} + 3\frac{\Delta b}{b} + 2\frac{\Delta c}{c} + 4\frac{\Delta d}{d}}{1 + 3 + 2 + 4}$$

$$\frac{\Delta X}{X} = \frac{10}{100} = 10%$$

The final answer: (A).
