Task: Answer the MCQ question.
Query: Which drug has a -3.856\% 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.) CCN1CCN(c2nc(S(=O)(=O)c3ccc(C)cc3)c(Cl)s2)CC1.Cl
b.) COC(=O)CSc1nnc(-c2cccnc2)n1-c1cccc(OC)c1
c.) CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](C)[C@H]1CCCO
d.) O=C(NCc1cccnc1)c1ccc(NC(=O)c2ccc(Br)cc2)cc1
Answer: c. CCO[C@@H]1OC(C(=O)Nc2ccccc2)=C[C@H](C)[C@H]1CCCO
