I had been asked this question in my homework.

I'd like to ask this question from Significant Figures in section Units and Measurements of Physics – Class 11

Answer 1

Right choice is (a) 5.9×10^3

The explanation is: Here the number of significant digits is 4. In standard scientific form, we need not consider the zeros after 9 and need to bring the value between 1 and 9 in the first place.
