Task: Answer the multiple choice question.
Question: Which compound has a 3.546% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(N/C(=C\c1ccco1)C(=O)N1CCOCC1)c1ccco1
[b] CCc1[nH]nc2c1C(c1ccc(C)o1)C(C#N)=C(N)O2
[c] CCOC(=O)CSc1n[nH]c(-c2cccnc2)n1
[d] C/C(CC(=O)Nc1cccc(C(F)(F)F)c1)=N\NC(=O)C1CCCCC1
Answer: b. CCc1[nH]nc2c1C(c1ccc(C)o1)C(C#N)=C(N)O2
