Task: Answer the multiple-choice question.
Question: Which drug has a 8.376\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) O=C(Oc1cccc(Nc2ncnc3ccccc23)c1)c1cccnc1
b.) S=C(Nc1ccc(Cl)cc1)NC1CCN(Cc2ccccc2)CC1
c.) COC(=O)c1cc(NC(=O)c2ccc(C)cc2)c(=O)oc1C
d.) CC(O)c1nc2c(c(=O)n(C)c(=O)n2C)n1C
e.) O=C(Nc1ccc(S(=O)(=O)N2CCCCC2)cc1)C1CC(=O)N(c2ccc(F)cc2)C1
Answer: d. CC(O)c1nc2c(c(=O)n(C)c(=O)n2C)n1C
