Which answer choice has 4 significant a.100.090090 b.143.29 c.0.05843 d. 0.1000 e. 00.0030020

c. 0.05843 would be the correct answer.

This is because significant figures are measured by starting from the first non-zero digit, and the first non-zero digit in option c. is 5, and it ends at 3. If you count all the figures from 5 through 3, you'll find that there's 4 figures in total (5, 8, 4, 3).
