Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.800% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc2c(c1)SC1=NCCS(=O)(=O)N12
b O=C(Oc1ccccc1)N(c1ccccc1)c1ccccc1
c Cc1cc(NC(=O)CN2C(=O)NC(C)(c3ccccc3)C2=O)no1
d COc1ccccc1C1CCN(c2ccc([N+](=O)[O-])cn2)CC1
Answer: b. O=C(Oc1ccccc1)N(c1ccccc1)c1ccccc1
