Task: Answer the multiple choice question.
Query: Which compound has a 5.276\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(NCC(c1cccs1)N1CCOCC1)c1cn(-c2ccccc2)nc1-c1ccc(Cl)cc1
[b] C=CCC1(CC=C)CCCN1C(=O)CC1C(=O)NCCN1Cc1cc(OC)cc(OC)c1
[c] Cn1c(=O)oc2cc(S(=O)(=O)Nc3ccccc3O)ccc21
Answer: a. O=C(NCC(c1cccs1)N1CCOCC1)c1cn(-c2ccccc2)nc1-c1ccc(Cl)cc1
