Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 3.388\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CCn1nnc2cc(C(=O)NCC(c3ccccc3OC)N(C)C)ccc21
b CCOC(=O)C1=C(C)N=C2SC(C(=O)OC)=CC(=O)N2C1c1cccc(OC)c1
Answer: b. CCOC(=O)C1=C(C)N=C2SC(C(=O)OC)=CC(=O)N2C1c1cccc(OC)c1
