Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.637\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Br.O=c1cc2c(n[nH]1)CCCC2
(b) CCOC(=O)C(=O)c1csc(NC(=O)COc2ccc(N(C)S(=O)(=O)c3ccc(F)cc3)cc2)n1
(c) CCOC(=O)C(Cc1ccccc1)C(=O)Nc1cccc(C)c1
(d) CC(=O)c1c(C)[nH]c(C(=O)N(C)C(c2ccccc2)c2ccccc2)c1C
Answer: a. Br.O=c1cc2c(n[nH]1)CCCC2
