Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.307\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CC(C)(C)OC(=O)NCCC(=O)N/N=C/c1cccc2cccnc12
b) O=C(O)Cn1nc(-c2ccccc2)oc1=O
c) COc1ccc(OC)c(NC(=O)CSc2nnnn2-c2ccc3c(c2)OCO3)c1
Answer: b. O=C(O)Cn1nc(-c2ccccc2)oc1=O
