Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.979\% 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 additional words.
Options:
[a] O=C(COC(=O)C1CCC1)NCc1ccc(Cl)cc1Cl
[b] O=C(CSc1nnc(COc2ccccc2)n1Cc1ccco1)c1ccc(F)cc1
[c] Nc1nc(SCn2nnc3ccccc3c2=O)n[nH]1
[d] CC(=O)n1cc([C@@H]2C=C(C(=O)N3CCN(C)CC3)O[C@H](OCc3ccc(CO)cc3)C2)c2ccccc21
[e] CN(C)/C=C/C(=O)c1ccc(-c2ccc(Cl)cc2Cl)o1
Answer: c. Nc1nc(SCn2nnc3ccccc3c2=O)n[nH]1
