Task: Answer the multiple-choice question.
Question: Which drug has a 18.906\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COC1=C/C(=C/c2c(N)n3c(nc2=O)sc2cc(S(C)(=O)=O)ccc23)C=CC1=O
b CCOc1ccc(CNC(c2ccccc2)c2ccccc2)cc1.Cl
c CCOC(=O)C1(CC2CCCCO2)CCN(Cc2cc(F)ccc2-n2cccn2)CC1
Answer: a. COC1=C/C(=C/c2c(N)n3c(nc2=O)sc2cc(S(C)(=O)=O)ccc23)C=CC1=O
