Problem statement: Answer the multiple choice question.
Query: Which drug has a -7.792\% 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 or b without using any additional words.
Options:
a. O=C(Nc1cccc(-c2nnc(-c3ccccc3)o2)c1)c1ccco1
b. CCOC(=O)c1c(NC(C)=O)sc2c(OCCN(CC)CC)c(Br)ccc12
Answer: b. CCOC(=O)c1c(NC(C)=O)sc2c(OCCN(CC)CC)c(Br)ccc12
