Task: Answer the multiple choice question.
Query: Which drug exhibits a -70.438\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) O=C(NCc1ccc(F)cc1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
b) COc1ccc(CCNC(=O)/C(=C/c2cccnc2)NC(=O)c2ccccc2)cc1
c) O=C1CC2(CCN(C(=O)COc3ccc(Cl)cc3)CC2)Oc2ccccc21
d) CCOC(=O)C1(Cc2cccc(F)c2)CCN(C(=O)c2cscn2)CC1
e) CCOC(=O)c1ccc(NC2=CC(=O)C(=O)c3ccccc32)cc1
Answer: c. O=C1CC2(CCN(C(=O)COc3ccc(Cl)cc3)CC2)Oc2ccccc21
