Answer:

Zero methylene groups

Explanation:

Hi, on one side you have the 2.4-dimethylhexane molecule as shown in the figure.

On the other side, you have the methylene group with the following structure:

=CH2

As can be seen there isn't any methylene group in the  2.4-dimethylhexane

Important: don't confuse the methylene group with the methyl group. Methyl group is -CH3 and there are two of them in this molecule.
