Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.922\% 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 CCC(=O)Nc1ccnc(-c2cccnc2)n1
b O=C(CN1C(=O)NC2(CCCCCC2)C1=O)NCc1cccs1
c Nc1nccnc1C(=O)OCC(=O)NNC(=O)c1ccccc1
d COc1ccc(-n2cc(-c3ccc(OC)c(OC)c3)[nH]c2=S)cc1
Answer: a. CCC(=O)Nc1ccnc(-c2cccnc2)n1
