Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 2.468\% 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 other words.
Options:
(a) O=C(CSc1nnc(Cc2cccs2)n1Cc1ccco1)Nc1cccc(Cl)c1
(b) O=C(CCCOc1ccc(Cl)cc1Cl)Nc1ccncc1
(c) Cc1ccc(NC(=O)COC(=O)CCNS(=O)(=O)c2ccc(C)c(C)c2)cc1
(d) O=C(NCCc1ccccc1)C1CCN(S(=O)(=O)c2ccc(-n3cnnn3)cc2)CC1
Answer: b. O=C(CCCOc1ccc(Cl)cc1Cl)Nc1ccncc1
