Task: Answer the multiple choice question.
Question: Which drug has a 0.612\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=S(=O)(Nc1ccc(-c2cn3ccccc3n2)cc1)c1ccccc1
(b) CCOC(=O)C1CCN(C(=O)COc2ccc(S(=O)(=O)N3CCOCC3)cc2C)CC1
(c) O=C(C[N+]12CCC(CC1)C(CO)C2)c1ccc(Br)cc1.[Br-]
(d) CCc1cccc(CC)c1NC(=S)N1CCn2cccc2C1c1cccnc1
(e) Cc1ccc(-n2c(C)nc3ccsc3c2=O)cc1
Answer: a. O=S(=O)(Nc1ccc(-c2cn3ccccc3n2)cc1)c1ccccc1
