c. 3
d. 4

Answer : The correct option is, (A) 1

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.

The rule apply for the multiplication and division is :

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

The given expression is:

In the given expression, 2860 has 3 significant figures, 0.915 has 3 significant figures, 1000 has 1 significant figure and has 2 significant figures. From this we conclude that 1 is the least significant figure in this problem. So, the answer should be in 1 significant figure.

Thus, the answer will be

Hence, the correct option is, (A) 1
