Task: Answer the multiple choice question.
Query: Which compound has a 4.463\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC(C)/C=C1\CCc2c([nH]c3ccccc23)C1=O
(b) Brc1ccc(-c2csc(/N=C/N3CCCC3)n2)cc1
(c) COc1ccc(-n2nc(C(=O)NCC(=O)N3CCCC(C)C3)c3ccccc3c2=O)cc1Cl
(d) Cc1cccc(C)c1NC(=O)CSc1nnnn1C
Answer: a. CC(C)/C=C1\CCc2c([nH]c3ccccc23)C1=O
