Task: Answer the multiple choice question.
Question: Which compound has a 4.573\% 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 O=C(c1cccc(Cl)c1)N1CCN(C(=O)c2ccco2)CC1
b O=C(c1ccccc1Sc1ccccc1[N+](=O)[O-])N1CCCCC1
c O=C(COc1ccccc1)NCC(=O)N/N=C/c1ccco1
d CCOC(=O)C1=C(c2ccccc2)NC(=S)NC1c1ccc(C)c([N+](=O)[O-])c1
Answer: c. O=C(COc1ccccc1)NCC(=O)N/N=C/c1ccco1
