Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.755\% 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] COc1ccc(Cc2nnc(SCC(=O)NCCc3ccccc3)o2)cc1
[b] NS(=O)(=O)c1ccc(NC(=O)CCCC(=O)O)cc1
[c] C#CC(C)(C)NC(=O)c1ccccc1OC
[d] CS(=O)(=O)N(CC(=O)N1CCCCCC1)c1cccc(Br)c1
Answer: b. NS(=O)(=O)c1ccc(NC(=O)CCCC(=O)O)cc1
