Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -22.598% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=c1c2ccccc2cnn1-c1ccc(Br)cc1
b) COC1=C(Nc2ccc(OC)cc2)C(=O)c2ccccc2C1=O
c) Cc1c(C(=O)NC2CCOC2)oc2c(F)cccc12
Answer: b. COC1=C(Nc2ccc(OC)cc2)C(=O)c2ccccc2C1=O
