Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.948\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:

(b) O=C(c1ccc(N2CCCCC2)c([N+](=O)[O-])c1)N(Cc1ccccc1)c1ccccn1
(c) O=C(CS(=O)(=O)c1cccc(C(F)(F)F)c1)Nc1ccccc1Cl
(d) CCOC(=O)N1CCN(C(=S)NC2CCCC2)CC1
Answer: b. O=C(c1ccc(N2CCCCC2)c([N+](=O)[O-])c1)N(Cc1ccccc1)c1ccccn1
