Answer:

C. He is a Levite

Explanation:

According to the Torah (specifically, Numbers 1:48-54), Levites were in charge of taking care of the tabernacle and ministering to the priests. As such, many also attribute this Levite's reluctance to his desire to maintain ritual purity. Again, however, this is not explicit in the text, and it is also plausible that Jesus is merely using the Levite as an example of someone whom the hearer would expect to obey the great commandment, but in fact does not view the victim as a neighbor.
