Answer:

D

Explanation:

Seeing the Lewis formula for each of the molecules, we can attempt to write the condensed structural formula for each.

What we notice is that while there are purely single bonds between the carbon atoms in the first molecule, there is a double bond in the second molecule and a triple bond in the third

What we can deduce from this is that these are alkanes , alkenes and alkynes

The alkynes have the strongest of the three bonds and thus they have the strongest bonds in the mix

Since molecule 3 is an alkyne, then we can say that it has the strongest of the bonds
