1. Non-zero digits are always significant.
2. Any zeros between two significant digits are significant.
3. A final zero or trailing zeros are significant only in decimal portion
Here,
Given measurement is 287.5 cm
By the first rule that non-zero digits are always significant, we conclude that in the given measurement, there are 4 significant figures
Therefore, Option (4) is correct.
Hope this answer is helpful.

CONCEPT TO BE IMPLEMENTED
SIGNIFICANT FIGURE
The figures are used in representing a number are called significant figures.
Thus 0,1,2,3,4,5,6,7,8,9 are significant figures or digits.
Therefore the numbers 2.123, 1.5034, 12.6826 contains 4, 5,6 significant figures respectively.
But the number like 0.00256 contains only three significant figures namely 2,5,6 as the leading two zeroes are used to fix the position of the decimal point.
