Task: Answer the multiple choice question.
Query: Which compound has a 1.248\% 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 other words.
Options:
[a] O=C(CSc1nnc(-c2ccc(F)cc2)c2ccccc12)Nc1cccc(Cl)c1
[b] Cc1cc(C)c(C(=O)N(CCN(C)C)CC2CCCN(Cc3ccccc3F)C2)o1
[c] O=C(NN1CCOCC1)c1cccc(COc2cccc(Br)c2)c1
[d] Cc1ccc(C(=O)C[n+]2ccc(-c3nnc4n3CCC4)cc2)cc1.[Br-]
Answer: a. O=C(CSc1nnc(-c2ccc(F)cc2)c2ccccc12)Nc1cccc(Cl)c1
