Task: Answer the MCQ question.
Question: Which drug has a 19.287\% 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, c, d, or e without using any other words.
Options:
[a] Cc1ccc(S(=O)(=O)c2nc(S(C)(=O)=O)sc2N2CCCC2)cc1
[b] COc1ccc(C2C(C(=O)c3ccccc3)=C(C)Nc3nc4ccccc4n32)c(OC)c1
[c] COc1ccc(C(=O)COc2ccc(F)cc2)c(O)c1C
[d] COc1ccc(CNc2nc(S(=O)(=O)c3ccccc3)c(Cl)s2)cc1OC
[e] Fc1cnc(N2CCOCC2)nc1N1CCOCC1
Answer: b. COc1ccc(C2C(C(=O)c3ccccc3)=C(C)Nc3nc4ccccc4n32)c(OC)c1
