Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.385\% 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) CCCN1CC23C=CC(O2)C(C(=O)O)C3C1=O
b) O=C(O)c1ccc(NC(CSCc2ccc(F)cc2)C(=O)O)c([N+](=O)[O-])c1
Answer: a. CCCN1CC23C=CC(O2)C(C(=O)O)C3C1=O
