Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.967\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C1CC(N2CCN(C(c3ccccc3)c3ccccc3)CC2)C(=O)N1
[b] COc1ccc(CCCc2nnc(SCC(=O)N/N=C\c3ccc(O)c(OC)c3)o2)cc1C
[c] Cc1ccc(CCC(=O)Nc2cc(Cl)ccc2Cl)o1
Answer: a. O=C1CC(N2CCN(C(c3ccccc3)c3ccccc3)CC2)C(=O)N1
