Task: Answer the multiple choice question.
Question: Which drug has a 20.416\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCc1c(C(=O)NC2CCCCC2)[nH]c(C)c1C(C)=O
(b) CCC1c2ccc(C)n2CCN1C(=O)Nc1ccccc1C(=O)OC
(c) O=C(N/N=C/C=C/c1ccccc1[N+](=O)[O-])c1cccnc1
Answer: a. CCc1c(C(=O)NC2CCCCC2)[nH]c(C)c1C(C)=O
