Problem statement: Answer the multiple choice question.
Query: Which compound has a 4.127\% 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 COc1cc(/C=C2/SC(=S)N(CC(=O)O)C2=O)ccc1OC(=O)c1ccco1
b Cc1cc(C)c2[nH]c(=O)c(C(c3nnnn3Cc3ccc4c(c3)OCO4)N3CCCC3)cc2c1
c CC12C(=O)N(Cc3ccccc3)C(=O)C1C1C=CC2C1
d O=C(O)c1ccc(O)cc1O
Answer: c. CC12C(=O)N(Cc3ccccc3)C(=O)C1C1C=CC2C1
