Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.296\% 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 additional words.
Options:
[a] O=C1N=c2ccccc2=C1c1sc(=S)n(Cc2ccccc2Cl)c1O
[b] COc1ccc(C(OC(=O)c2ccco2)C(=O)NC2CCCC2)cc1OC
[c] CCc1nnc(NC(=O)CN2C(=O)c3ccccc3C2=O)s1
[d] Cc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)CSc1nccn1C
Answer: a. O=C1N=c2ccccc2=C1c1sc(=S)n(Cc2ccccc2Cl)c1O
