Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.824\% 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, d, or e without using any additional words.
Options:
a) COc1ccc2c(C)cc(=O)[nH]c2c1
b) COc1ccc(NC(=O)CN(C)CC(=O)Nc2ccc(Cl)cc2[N+](=O)[O-])cc1
c) COc1ccc(CCNC(=O)COC(=O)c2ccc([N+](=O)[O-])o2)cc1
d) Cc1cc(NCCN)nc2ccccc12.O=[N+]([O-])O
e) Cc1nnsc1C(=O)N/N=C/c1ccc2ccccc2c1O
Answer: a. COc1ccc2c(C)cc(=O)[nH]c2c1
