Task: Answer the multiple choice question.
Question: Which drug has a 4.290\% 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 additional words.
Options:
a) O=C1OCc2cc(NC(=O)C3COc4ccccc4O3)ccc21
b) CCn1c(C)nc2cc(S(=O)(=O)N3CCCCC3)ccc21
c) Cl.O=C(COc1ccc(Cl)cc1Cl)NCCCn1ccnc1
Answer: a. O=C1OCc2cc(NC(=O)C3COc4ccccc4O3)ccc21
