Explanation:

Step1: Identify longest carbon - chain for a

The longest carbon - chain has 7 carbon atoms. There are two methyl groups at positions 2 and 5.
The IUPAC name is 2,5 - dimethylheptane.

Step2: Identify parent ring and substituent for b

The parent ring is cyclohexane. There is a chloro - substituent and a methyl - substituent at the same carbon. The IUPAC name is 1 - chloro - 1 - methylcyclohexane.

Step3: Identify parent ring and substituents for c

The parent ring is cyclopentane. There are two methyl groups at positions 1 and 3. The IUPAC name is 1,3 - dimethylcyclopentane.

Answer:

a. 2,5 - dimethylheptane
b. 1 - chloro - 1 - methylcyclohexane
c. 1,3 - dimethylcyclopentane
