Problem statement: Answer the multiple-choice question.
Query: Which drug has a 2.401\% 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: O=c1c2ccccc2nc(-c2ccco2)n1-c1nccs1
b: CCOC(=O)NC(=O)/C(C#N)=C\Nc1sccc1C(=O)OC
c: O=C(CSc1nc2[nH]ncc2c(=O)[nH]1)NCCc1ccccc1
d: COc1ccc(COC(=O)N/N=C(\C)CC(=O)Nc2c(C)cc(C)cc2C)cc1
Answer: a. O=c1c2ccccc2nc(-c2ccco2)n1-c1nccs1
