Answer:  0.11

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.

All non-zero numbers are always significant.

All zero’s between integers are always significant.

All zero’s preceding the first integers are never significant.

All zero’s after the decimal point are always significant.

The rule apply for multiplication and division is :

The least precise number determines the number of significant figures in the answer.

As we are given :  $\frac{0.25}{22.1176}=0.11303$

As the digit 0.25 has 2 significant figures and 22.1176 has 6 significant figures, thus the answer must have 2 significant figures.

Thus the correct answer is 0.11
