Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.959% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) NS(=O)(=O)c1ccc2c(c1)C1C=CCC1C(C1CC=CCC1)N2
(b) C=CCSC1=N/C(=C\c2cc(OCC)c(OC(C)=O)c([N+](=O)[O-])c2)C(=O)S1
Answer: b. C=CCSC1=N/C(=C\c2cc(OCC)c(OC(C)=O)c([N+](=O)[O-])c2)C(=O)S1
