Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.243\% 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.) COc1ccc(S(=O)(=O)N2CCSC2c2ccccc2)cc1
b.) O=C(O)/C=C\C(=O)Nc1ccc(N2CCN(c3ccc(Cl)c(Cl)c3)CC2)cc1
c.) COc1ccc2cc(C#N)c(N3CCN(C(=O)c4ccccc4C)CC3)nc2c1
d.) CC1C(c2ccccc2)=[N+]([O-])C2(CCCC2)N1O
Answer: d. CC1C(c2ccccc2)=[N+]([O-])C2(CCCC2)N1O
