Task: Answer the multiple choice question.
Question: Which drug exhibits a 17.843\% 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 other words.
Options:
a CCOC(=O)c1c(C)[nH]c(C(=O)OCC(=O)Nc2sccc2C(N)=O)c1C
b O=C(N/N=C/c1ccco1)c1cc(-c2cccs2)[nH]n1
Answer: b. O=C(N/N=C/c1ccco1)c1cc(-c2cccs2)[nH]n1
