Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.413\% 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(NC(=O)CSc2cccc[n+]2[O-])sc(C(=O)Nc2ccccc2)c1C
[b] O=C(CCc1nc2ccccc2c(=O)[nH]1)OCC(=O)N1CCN(S(=O)(=O)c2ccccc2)CC1
[c] CCSc1nn2c(=O)c3ccccc3nc2s1
[d] CC(=O)O.NC(N)=N/N=C/c1c(Cl)cccc1Cl
Answer: b. O=C(CCc1nc2ccccc2c(=O)[nH]1)OCC(=O)N1CCN(S(=O)(=O)c2ccccc2)CC1
