Task: Answer the multiple choice question.
Question: Which compound has a -1.521\% 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) CNC(=O)CSc1nccn1Cc1ccc(Cl)cc1
b) O=C(N/C(=C/C=C/c1ccccc1)C(=O)N1CCOCC1)c1ccccc1Cl
c) O=C(c1ccncc1)N1CCN(S(=O)(=O)c2cccc(C(F)(F)F)c2)CC1
Answer: a. CNC(=O)CSc1nccn1Cc1ccc(Cl)cc1
