Task: Answer the multiple-choice question.
Question: Which compound exhibits a 13.298% 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 O=C(c1cnn2c(C(F)(F)F)cc(-c3cccs3)nc12)N1CCN(C(c2ccccc2)c2ccccc2)CC1
b CN1CCN(c2c(F)cc([N+](=O)[O-])c(N)c2Br)CC1
c CS(=O)(=O)c1ccc(C(=O)NC2CCCc3ccccc32)cc1
d Cn1c(=O)oc2cc(S(=O)(=O)Nc3ccc4c(c3)OCO4)ccc21
Answer: a. O=C(c1cnn2c(C(F)(F)F)cc(-c3cccs3)nc12)N1CCN(C(c2ccccc2)c2ccccc2)CC1
