Question
**Question:**
Which would be the major isolated organic product of the reaction shown?

**Reaction Setup:**
- Reactants: A benzene ring attached to a terminal alkyne
- Reagents: Na, NH₃ (liquid)

**Options:**
A) An alkane with an arene attached  
B) A cis- alkene  
C) A trans- alkene  
D) An alkene that is neither cis- nor trans-  
E) A different product or a mixture of more than one of the choices in equal amounts  

**Explanation:**
This image likely depicts a partial reduction reaction of an alkyne using sodium in liquid ammonia, also known as the Birch reduction. This method typically converts alkynes to trans-alkenes. Hence, option C may represent the major product.
