Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.255\% human ether-à-go-go related gene (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.) O=C(CSc1nnc(-c2cccnc2)n1Cc1ccccc1)NCc1ccccc1
b.) O=C(CSCc1ccc(Cl)cc1)Nc1ccc2c(c1)OCO2
c.) CCN1CCN(C(=O)c2ccc(OC)c(S(=O)(=O)Nc3ccc(C)cc3)c2)CC1
d.) COC1=C(Nc2ccccc2)C(=O)c2ccccc2C1=O
Answer: d. COC1=C(Nc2ccccc2)C(=O)c2ccccc2C1=O
