Problem statement: Answer the multiple-choice question.
Question: Which drug has a 3.277\% hERG inhibition at 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(NCCN1CCN(c2cccc(Cl)c2)CC1)c1ccc(CSc2nc3ccncc3[nH]2)cc1
[b] CC(OC(=O)CC1CCCCC1)C(=O)Nc1ccc(S(N)(=O)=O)cc1
[c] Cl.NC(N)=NC(N)=Nc1cccc(Cl)c1
[d] COc1ccc(C(=O)NNC(=O)CN2CCC(n3nnc4cc(C(F)(F)F)ccc43)CC2)cc1
Answer: c. Cl.NC(N)=NC(N)=Nc1cccc(Cl)c1
