Task: Answer the multiple-choice question.
Question: Which drug has a -3.785\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCN(CC)C(=O)c1cccc(NC(=O)C2=COCCO2)c1
b. CCn1nnc(NC(=O)c2ccccc2Br)n1
c. COc1nc(-c2ccccc2)ccc1-c1noc(-c2ccco2)n1
d. O=C1C(C2=NC(c3ccccn3)C3C(=O)N(c4ccc(OC(F)(F)F)cc4)C(=O)C23)=C(O)c2ccccc21
Answer: c. COc1nc(-c2ccccc2)ccc1-c1noc(-c2ccco2)n1
