Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.978\% human ether-à-go-go related gene (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] Cc1cccc(C(=O)NC(=S)Nc2ccc(Cc3ccncc3)cc2)c1
[b] COc1ccccc1-c1nnc(-c2ccc(N3CCOCC3)cc2)o1
[c] C=CC(=O)NC(NC(=O)C=C)c1ccc(Br)cc1
[d] O=C(NC1CCCCC1)C(c1ccco1)N(C(=O)C(F)(F)F)C1CC1
Answer: c. C=CC(=O)NC(NC(=O)C=C)c1ccc(Br)cc1
