Task: Answer the multiple choice question.
Question: Which compound has a 1.680\% 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) Cl.O=C(O)/C=C/c1ccc(Cn2ccnc2)cc1
(b) CC(C)CCn1nnnc1C(c1ccccc1)N1CCC(C(N)=O)CC1
(c) Cc1nnc2c(SC(C)C)nc3ccccc3n12
Answer: a. Cl.O=C(O)/C=C/c1ccc(Cn2ccnc2)cc1
