That's Correct!
It's Wrong!
The number of significant figures in a measurement is determined by the precision of the measuring tool and the certainty of the digits reported. In the case of the mass of 0.034 grams:
The leading zero is not considered significant.
The trailing zero after the decimal point is significant.
The non-zero digit "3" is significant.
So, there are two significant figures in the mass of 0.034 grams. Therefore, the correct option is 2.
