Task: Answer the multiple-choice question.
Question: Which drug has a 19.656\% 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 or b without using any other words.
Options:
(a) C=CCc1cc(C=C2C(=O)N(C)C(=O)N(C)C2=O)cc(OCC)c1OCc1ccccc1
(b) CCCCC(=O)/C=C/n1c(=S)oc2ccccc21
Answer: b. CCCCC(=O)/C=C/n1c(=S)oc2ccccc21
