Problem statement: Answer the multiple-choice question.
Question: Which drug has a -21.302\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CSc1sccc1/C=C(/C#N)C(=O)c1ccco1
b) O=C(NCCCN1CCOCC1)c1ccc2c(=O)n(Cc3ccc(Cl)cc3)c(=S)[nH]c2c1
c) O=C(c1sc2cc([N+](=O)[O-])ccc2c1Cl)N1CCCCC1
Answer: c. O=C(c1sc2cc([N+](=O)[O-])ccc2c1Cl)N1CCCCC1
