#100# has one significant figure.

Explanation:

As the number is given, it has 4 significant figures.

The zero's are part of the number, they are not just place holders making the number 10 times bigger or smaller.

#100.1# has 4 significant figures in the same way that #135.1 #would.

#100# has 1 significant figure

In this case, 2 and 3 significant figures would also be 100
