Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.707% human ether-à-go-go related gene (hERG) inhibition at a concentration of 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(O)c1cc2cc(Cl)ccc2oc1=O
b O=C(NCc1ccccc1F)C(c1ccccc1)c1ccccc1
c Cc1ccccc1NC(=S)NN1CCN(C)CC1
d Cc1cc(C)n2[nH]c(=O)c(N=Nc3cccc(Cl)c3)c2n1
Answer: a. O=C(O)c1cc2cc(Cl)ccc2oc1=O
