Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.550\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(COc1ccccc1)N1CCNC1=O
b: O=C(N/N=C/c1ccccn1)c1cc(-c2ccncc2)nc2ccccc12
c: CCn1c2ccc(OC)cc2c2nc3ccccc3nc21
d: COc1ccc(C(=O)N2CCN(C(=O)Cc3ccccc3)CC2)cc1.O=C(O)C(=O)O
Answer: d. COc1ccc(C(=O)N2CCN(C(=O)Cc3ccccc3)CC2)cc1.O=C(O)C(=O)O
