Answer 1

Answer;

`B`

Explanation;

Mathematically, as a rule; in cases like this, we use the least number of significant figures

Looking at the values given, the least is 3 significant figures

So, that is what we are to use

However, we need to get the exact value by performing the division as follows;

`(9.52)/(0.36*0.247*3.9)\text{ = 27.5}`

The value given is the correct number of significant figures from the division

So, now we select the correct choice;

The correct choice is thus option B
