Task: Answer the multiple-choice question.
Query: Which compound exhibits a -5.948\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(=O)N1CC=CC1(C)C(=O)O
b: Cc1ccc(OC(=O)CCS(=O)(=O)c2ccc(C)cc2)cc1
c: O=C(c1ccccc1F)N1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1
d: Cc1ccc(C)c(-n2c(-c3ccncc3)n[nH]c2=S)c1
Answer: c. O=C(c1ccccc1F)N1CCN(S(=O)(=O)c2ccc(Br)cc2)CC1
