Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 12.518\% 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, or c without using any additional words.
Options:
a CN1C(=O)/C(=C/c2ccccc2Cl)Sc2ccc(C(=O)NCc3cccnc3)cc21
b Cc1cc(N2CCN(C)CC2)nc2ccc(NC(=O)c3ccccc3F)cc12
c O=C(O)c1cc2cc(Oc3ccccc3)ccc2[nH]1
Answer: c. O=C(O)c1cc2cc(Oc3ccccc3)ccc2[nH]1
