Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.295\% 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) COc1cc(/C=N/NC(N)=S)ccc1OCC(=O)N1CCOCC1
(b) CCOc1cc(NC(=O)c2ccco2)c(OCC)cc1NC(=O)c1cc(OC)c(OC)c(OC)c1
(c) Cc1cccc(NS(=O)(=O)c2ccc(C(=O)NCC3(N4CCCCC4)CCCCC3)cc2)c1C
(d) O=C1CC(Cc2ccc(Br)cc2)C(=O)N1c1ccccc1
Answer: a. COc1cc(/C=N/NC(N)=S)ccc1OCC(=O)N1CCOCC1
