Task: Answer the multiple-choice question.
Query: Which drug has a 4.618\% 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: CC(C)CNC(=O)CSc1ccc(Cl)cc1
b: O=C(NC(=S)N1CCN(c2nc(-c3ccccc3)cs2)CC1)c1cncc(Br)c1
c: Cc1ccc2c(c1)n(S(=O)(=O)c1cccs1)c(=O)n2S(=O)(=O)c1cccs1
d: O=C(Nc1ccccc1F)Nc1ccccc1Br
Answer: d. O=C(Nc1ccccc1F)Nc1ccccc1Br
