Task: Answer the multiple choice question.
Question: Which compound has a -3.207\% 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 COc1ccc(CCN2CC34C=CC(O3)C(C(=O)NCc3ccccc3)C4C2=O)cc1OC
b COCCC(=O)N1CCC(Oc2ccc(C(=O)N(C)C3CCCCC3)cc2)CC1
c CC(C(=O)Nc1ccccc1)N(C)Cc1cccs1
d CCC(C)[C@H](NC(=O)NCc1ccc(Cl)cc1)C(=O)O
Answer: d. CCC(C)[C@H](NC(=O)NCc1ccc(Cl)cc1)C(=O)O
