Answer:

2.00

Explanation:

Significant figures:

Any leading non-zero number is a significant figure.
Zeroes between a decimal point and a non-zero number are significant.
Zeroes after the decimal point (that is, a decimal point after a leading non-zero number) are significant.

You have three significant figures if you round 2.001234 to 2.00 only.
