Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.455\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. CC(=O)Nc1ncnc2c1c(-c1ccc(Cl)cc1)nn2C(C)(C)C
b. Cn1c(=NC(=O)CS(=O)(=O)c2ccccc2)sc2ccccc21
c. COc1ccc2[nH]c(C)c(CCNCc3cccnc3)c2c1.O=C(O)C(=O)O
d. COc1ccc(CCNS(=O)(=O)c2ccc3c(c2)CCN3C(=O)CCC(=O)O)cc1OC
e. CCN1CCc2nc(N)sc2C1
Answer: a. CC(=O)Nc1ncnc2c1c(-c1ccc(Cl)cc1)nn2C(C)(C)C
