Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.802\% 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) CC1=NC(C(F)(F)F)(C(F)(F)F)C(C#N)=C(C)N1
b) CCC(=O)N1CCN(c2nnc(-c3ccccc3)c3ccccc23)CC1
c) O=C(N/C(=C\c1ccco1)C(=O)N1CCCC1)c1ccccc1
d) COC(=O)c1ccc(C2CC(=O)Nc3cc(OC)c(OC)cc32)cc1
Answer: b. CCC(=O)N1CCN(c2nnc(-c3ccccc3)c3ccccc23)CC1
