Problem statement: Answer the multiple choice question.
Query: Which compound has a 22.925\% 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 other words.
Options:
a: Cn1ncc(Br)c1NC(=O)Nc1ccccc1
b: Nc1ccc(S(=O)(=O)NC2=NCCCCC2)cc1
c: CCOC(=O)C(C)Sc1ncnc2c1c(-c1ccccc1)cn2-c1ccc(OC)cc1
d: O=C(CCCN1C(=O)C(c2ccccc2)Oc2cccnc21)NCc1ccccc1Cl
Answer: d. O=C(CCCN1C(=O)C(c2ccccc2)Oc2cccnc21)NCc1ccccc1Cl
