Task: Answer the multiple choice question.
Question: Which drug has a 8.819\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C(CS(=O)(=O)c1ccccc1)N1CCN(c2ccccc2)CC1
b. O=C(CN(C(=O)c1csnn1)c1ccc(Cl)cc1)NCc1ccc2c(c1)OCO2
c. C=C1CCN([C@@H](Cc2ccccc2)C(=O)NCc2ccc(Cl)cc2)S(=O)(=O)c2ccccc21
d. O=C(O)CC1SC(=O)NC1=O
Answer: d. O=C(O)CC1SC(=O)NC1=O
