Problem statement: Answer the multiple-choice question.
Question: Which drug has a 7.921\% 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, or c without using any other words.
Options:
a CCOC(=O)c1c(NC(=O)C2c3ccccc3Oc3ccccc32)sc(C(N)=O)c1C
b CCC(C)NC(=O)CCn1c(-c2ccc(F)cc2)cc(C(C)=O)c1C
c CC(=O)Nn1c(-c2ccccc2)cc2ccccc21
Answer: a. CCOC(=O)c1c(NC(=O)C2c3ccccc3Oc3ccccc32)sc(C(N)=O)c1C
