Task: Answer the multiple choice question.
Query: Which compound exhibits a 1.139\% 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) COCCn1c(CN(C)Cc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
(b) Cc1cc2c(cc1C)/C(=C\C(N)=O)NC(C)(C)C2
(c) CCc1ccc(NC(=O)[C@H](C)NC(=O)C2CCN(C(=O)[C@@H](NC(=O)OC(C)(C)C)C(C)C)CC2)cc1
Answer: b. Cc1cc2c(cc1C)/C(=C\C(N)=O)NC(C)(C)C2
