Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 14.777\% 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: CCOc1[nH]n(-c2ccccc2)c(=O)c1C=Nc1ccc(F)cc1F
b: C=C1CC2C(CCC3(C)C2CCC3(O)C(C)=O)C2(C)CCC(=O)C=C12
c: Cc1cccc(C(=O)Nc2ccc3c(c2)C(=O)N(CC(C)C)C3=O)c1
d: Cc1ccc(N(C(=O)c2csnn2)C(C(=O)NC(C)(C)C)c2cccnc2)cc1C
Answer: a. CCOc1[nH]n(-c2ccccc2)c(=O)c1C=Nc1ccc(F)cc1F
