Here are the essential concepts you must grasp in order to answer the question correctly.
Grignard Reagents
Grignard reagents are organomagnesium compounds represented as R-MgX, where R is an organic group and X is a halogen. They are highly reactive and serve as nucleophiles in organic synthesis, allowing for the formation of carbon-carbon bonds. When added to electrophiles, such as carbonyl compounds or epoxides, they can facilitate the synthesis of alcohols and other functional groups.

Ethylene Oxide
Ethylene oxide is a three-membered cyclic ether that is highly reactive due to its strained ring structure. It can undergo nucleophilic attack, making it a useful substrate for reactions with Grignard reagents. When a Grignard reagent attacks ethylene oxide, it opens the epoxide ring, leading to the formation of an alcohol after subsequent protonation.

Nucleophilic Attack
Nucleophilic attack is a fundamental reaction mechanism in organic chemistry where a nucleophile donates an electron pair to an electrophile, forming a new bond. In the context of Grignard reagents and ethylene oxide, the nucleophile (Grignard reagent) attacks the electrophilic carbon in the epoxide, resulting in ring opening and the formation of a new carbon-carbon bond, ultimately leading to the desired alcohol.
