Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 20.227\% 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) Cc1ccc(CSc2nc3sc(C)c(C)c3c(=O)n2Cc2ccco2)cc1
b) O=S(=O)(Cc1ccc(Cl)cc1)Nc1ccc2c(c1)OCO2
c) O=C1COc2ccc(C(=O)COC(=O)Cc3ccc(Cl)cc3)cc2N1
d) COCCn1c(-c2ccc(-c3ccccc3Cl)o2)nc2c1c(=O)[nH]c(=O)n2CC(C)C
Answer: d. COCCn1c(-c2ccc(-c3ccccc3Cl)o2)nc2c1c(=O)[nH]c(=O)n2CC(C)C
