Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.637\% 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) CCOC(=O)c1c(NS(=O)(=O)c2cccc(OC)c2)sc2c1CCC2
(b) CC1=NOC(=O)/C1=C\c1ccc2c(c1)OCO2
(c) Cc1cccc(N(CC(=O)NC(C)(C)C)C(=O)CS(=O)CC(=O)Nc2ccc(F)cc2)c1
(d) NC(=O)NC(=O)CSc1nc(C2CCCCC2)n(-c2ccccc2)n1
Answer: b. CC1=NOC(=O)/C1=C\c1ccc2c(c1)OCO2
