Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.851\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCCC(=O)Nc1nn(CCC)c2nc3ccccc3cc12
b: O=C(O)c1cccc2c1C(=O)c1ccc(N3CCCCC3)cc1S2(=O)=O
c: CCn1c(-c2ccc3[nH]c(C)c(C)c3c2)n[nH]c1=S
Answer: c. CCn1c(-c2ccc3[nH]c(C)c(C)c3c2)n[nH]c1=S
