Task: Answer the multiple-choice question.
Question: Which compound has a 5.385\% 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(N(CC(=O)Nc2ccc(S(=O)(=O)N3CCCC3)cc2)S(C)(=O)=O)cc1OC
[b] CCOc1cc(/C=C2\SC(N3CCCC(C)C3)=NC2=O)ccc1O
[c] Cc1cc(C)cc(NS(=O)(=O)c2cc(Br)cnc2N)c1
[d] CCC(=O)Nc1ccc2c(c1)nc(CCNC(=O)c1ccco1)n2C
Answer: a. COc1ccc(N(CC(=O)Nc2ccc(S(=O)(=O)N3CCCC3)cc2)S(C)(=O)=O)cc1OC
