Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.608\% 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 additional words.
Options:
a Cc1onc(-c2ccccc2)c1C(=O)NC(=S)Nc1sc2c(c1C#N)CCCC2
b O=C(CNC(=O)C1CCCCC1)NNC(=O)c1ccc(Cl)cc1Cl
c O=C(NCCC1=CCCCC1)c1ccc([N+](=O)[O-])cc1
d O/N=C1\CCc2cc(Cl)ccc21
Answer: a. Cc1onc(-c2ccccc2)c1C(=O)NC(=S)Nc1sc2c(c1C#N)CCCC2
