Task: Answer the MCQ question.
Question: Which compound has a 2.547\% 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, or c without using any other words.
Options:
[a] CCOC(=O)/C(=C/c1c[nH]c2ccccc12)NC(C)=O
[b] CCCN(C(=O)c1cccc(S(=O)(=O)N2CCN(C)CC2)c1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
[c] COC(c1ccccc1)(c1ccccc1)C(Oc1nc(C)cc(C)n1)C(=O)O
Answer: a. CCOC(=O)/C(=C/c1c[nH]c2ccccc12)NC(C)=O
