Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.175\% 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, b, c, or d without using any additional words.
Options:
a CCOC(=O)c1ccc(NC(=O)CSc2nc3ncccc3[nH]2)cc1
b COc1ccc(/C(N)=N/OC(=O)c2cccc([N+](=O)[O-])c2)cc1OC
c COc1ccc(C(=O)CC(=O)C(=O)Nc2ccccc2OC)cc1
d Cc1cc(C)nc(SCc2cc(=O)c(OC(=O)c3cc([N+](=O)[O-])ccc3Cl)co2)n1
Answer: a. CCOC(=O)c1ccc(NC(=O)CSc2nc3ncccc3[nH]2)cc1
