Question
**Question:**
Amalumastat is a medication that causes the arteries to increase in diameter so more blood can flow through. Which layer of the artery is this medication targeting?

**Options:**
a. The tunica adventitia  
b. The tunica intima  
c. The tunica sclerosa  
d. The tunica externa  
e. The tunica media  

**Explanation:**
This question is designed to assess knowledge of the anatomical layers of arterial walls and how medications can affect them. The relevant layer for increasing arterial diameter is typically the tunica media, which consists of smooth muscle that can contract or relax to change the vessel's diameter. 

Note: The option "c. The tunica sclerosa" is not a standard term for arterial layers, indicating a possible error or an attempt to test the student's alertness to detail.
