Task: Answer the multiple choice question.
Question: Which compound exhibits a -29.705\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: c1ccc(OCCSc2ncnc3nc[nH]c23)cc1
b: C=CCn1c(SC2CCOC2=O)nc2sc(CC)cc2c1=O
c: Cc1ccccc1C(=O)NC1CC2CCCC(C1)N2C(=O)Nc1ccccc1
Answer: b. C=CCn1c(SC2CCOC2=O)nc2sc(CC)cc2c1=O
