The Correct Option is A

Solution and Explanation

The structure $CH_3 -CH_2 - CH_2 -\underset{\overset{|}{C}H_3}{\overset{\underset{|}{C}H_3}{C}}-\underset{\overset{|}{C}H_3}{C}H - CH_2 -CH_3$ while writing IUPAC name, alkyl groups are written in alphabetical priority, thus lower locant $3$ is assigned to ethyl.

Organic Chemistry - Some Basic Principles and Techniques

Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
