Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.403\% human ether-à-go-go related gene (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] Nc1nonc1NC(=O)CSc1nc2ccccc2s1
[b] O=C(O)/C=C/C(=O)Nc1ccc(Oc2ccc(NC(=O)/C=C/C(=O)O)cc2)cc1
[c] O=C(O)Cc1ccccc1C(=O)O
[d] S=C(NNc1ccnc2cc(Cl)ccc12)Nc1ccc(Cl)cc1Cl
Answer: c. O=C(O)Cc1ccccc1C(=O)O
