Task: Answer the multiple choice question.
Question: Which compound has a 2.575\% 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] NC(CO)(CO)CO.O=C(c1ccccc1)c1ccc2n1CCC2C(=O)O
[b] Cc1cc(C)cc(NC(=O)CSc2nnc(CNC(=O)c3cccs3)o2)c1
[c] CCCc1nnc(NC(=O)c2ccncc2)s1
[d] COc1ccccc1N(CC(=O)N1CCCCCC1)S(C)(=O)=O
Answer: c. CCCc1nnc(NC(=O)c2ccncc2)s1
