Answer:
D

the zero is trailing with a decimal so it counts. A is wrong because you can't round up, C is too many SF and E is wrong because a negative exponent would give you .001250
Answer: D
Explanation:
Not A: You don’t round up to 1251 because 3 is less than 5
Not B: That’s more than 4 sig figs
Not C: More than 4 sig figs
D: 1.250 has 4 sig figs and 1250 is the correct answer
Not E: negative exponent makes it into decimal which is way off
