Answer :- Option 2 90 mm is correct.

Explanation :-

In the given diagram, we consider the starting point of measurement the value where the mouth of the earthworm is pointed i.e 1.5 cm.

So if we count from 1.5 cm that is the start point and then we see the end point i.e 10.5 cm we get,

10.5 - 1.5 = 9.0 cm

So the length of the earthworm is 9.0 cm as seen from the scale.

Now to convert cm into mm, we need to know that:

1 cm = 10 mm

Thus, to convert 9.0 cm to mm

we need to multiply 9 by 10

9 X 10 = 90

So the answer is 90 mm.
