Number of π bonds and σ bonds in the following structure is–



A. 6, 19

B. 4, 20

C. 5, 19

D. 5, 20

Each double bond has one pie bond. The single bond is sigma bond.

So, we can see in the above diagram that Napthalene molecule has 5 double bond and 19 sigma bonds.

Thus, Option (iii) is the correct answer.
