**Question:**

What is the major product of the following reaction?

**Reaction Details:**

1. Starting Material: A molecule featuring an alkyne group attached to a branching alkyl group.
2. Reagents: 
   - Step 1: NaNH₂ 
   - Step 2: A molecule with a bromine atom attached to a branching alkyl group.

**Answer Choices:**

- Option A: A molecule with an alkene group attached to a branching alkyl group.
- Option B: A molecule with a longer carbon chain featuring two branching points and an alkene group.
- Option C: A molecule with an alkene group attached at one end to a branching point, forming a shorter chain than Option B.

**Explanation:**

This question involves using a base (NaNH₂) to generate an acetylide ion from the terminal alkyne, which then participates in a nucleophilic substitution reaction with the alkyl bromide to form a new carbon-carbon bond.
