Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.881% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(CN1CCN(C(=O)C2CCCO2)CC1)Nc1cc(C(F)(F)F)ccc1Cl
[b] O=C(O)c1cc(-c2ccccc2)nn1CC1CC(c2cccnc2)=NO1
[c] O=C(/C=C/c1cccs1)N1CCN(c2ccccc2)CC1
[d] CN(C(=O)Cn1cnc([N+](=O)[O-])n1)C1CCCCC1
Answer: c. O=C(/C=C/c1cccs1)N1CCN(c2ccccc2)CC1
