Task: Answer the MCQ question.
Question: Which drug exhibits a 8.285\% 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 additional words.
Options:
a O=C(NCCc1ccccc1)C1CCC(=O)N1CCc1ccccc1
b O=C(Nc1ccccn1)NC(C(F)(F)F)C(F)(F)F
c COc1ccc2nc(SCC(=O)C(C)(C)C)[nH]c2c1
d C/C(CC(=O)Nc1ccccc1C)=N\NC(=O)Cc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: b. O=C(Nc1ccccn1)NC(C(F)(F)F)C(F)(F)F
