Task: Answer the MCQ question.
Query: Which drug exhibits a -4.468\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC1CC(C)CN(c2cc3c(cc2[N+](=O)[O-])C(=O)N(c2ccccc2)C3=O)C1
b Cc1cccc(NC(=O)c2ccc(C3SCC(=O)N3CCc3ccccc3)cc2)c1
c CCCc1nn(C)c(C(=O)Nc2ccc(C)c(C)c2)c1Cl
d O=C(c1ccccc1F)N1CCN(c2ccccn2)CC1
e O=C1CCCCCN1C(=O)c1ccc(C(=O)N2CCCCCC2=O)cc1
Answer: c. CCCc1nn(C)c(C(=O)Nc2ccc(C)c(C)c2)c1Cl
