Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 7.536\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1cc(C(=O)Nc2cc(C(F)(F)F)ccc2-n2cncn2)cc(OC)c1OC
[b] COc1cccc(NC(=O)c2ccc[n+](C)c2)c1.[I-]
[c] O=C(/C=C/N1CCc2ccccc21)C(F)(F)Cl
[d] Cc1ccc(C)c(-c2nc3ccc(N)cc3[nH]2)c1
[e] COc1ccc(C(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)c(OC)c1OC
Answer: c. O=C(/C=C/N1CCc2ccccc21)C(F)(F)Cl
