Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.284\% 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) CN=c1scc(-c2cccs2)n1/N=C(\C)c1ccco1
b) Cn1c(=O)c2c(nc(Br)n2CCSc2ncccn2)n(C)c1=O
Answer: a. CN=c1scc(-c2cccs2)n1/N=C(\C)c1ccco1
