Problem statement: Answer the multiple choice question.
Question: Which drug has a 13.860\% 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 additional words.
Options:
[a] O=C(Cc1ccccc1F)c1ccc(O)cc1O
[b] Cc1ccc(NC(=O)c2cccc3c2C(=O)N(C2CCCCC2)C3)c(C)c1
[c] CCOC(=O)c1ccc(NC(=O)CSc2nnc(-c3ccncc3)n2C)cc1
[d] O=C(O)[C@@H](O)c1ccccc1
Answer: a. O=C(Cc1ccccc1F)c1ccc(O)cc1O
