Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.015\% 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, or c without using any other words.
Options:
a COc1cc(/C=N/NC(=O)NC23CC4CC(CC(C4)C2)C3)ccc1O
b CC(C)Cc1cc(C(=O)N2N=C(C(F)F)CC2(O)C(F)F)c2ccccc2n1
c O=C(c1cc(Cl)ccc1Cl)N1CCN(c2ccccn2)CC1
Answer: c. O=C(c1cc(Cl)ccc1Cl)N1CCN(c2ccccn2)CC1
