Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 18.592\% 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(N/N=C/c1ccco1)c1cc(-c2ccc3ccccc3c2)n[nH]1
b CCOC(=O)c1c(NC(=O)/C=C/c2ccc3c(c2)OCO3)sc(C)c1CC
Answer: b. CCOC(=O)c1c(NC(=O)/C=C/c2ccc3c(c2)OCO3)sc(C)c1CC
