Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.456\% 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=C(Nc1ccc(Br)cc1Cl)c1ccc2c(=O)n3c(nc2c1)CCC3
(b) Cc1cc(C)c2sc(N)nc2c1
(c) Cc1ccc(NC(=S)NC(=O)c2cncc(Br)c2)c(C)c1
(d) Br.O=C(Cn1c(NCCCO)nc2ccccc21)c1ccco1
(e) Cc1ccc(C(=O)Nc2ccccc2C(=O)O)cc1S(=O)(=O)NC1CCCCC1
Answer: a. O=C(Nc1ccc(Br)cc1Cl)c1ccc2c(=O)n3c(nc2c1)CCC3
