Task: Answer the multiple-choice question.
Question: Which drug exhibits a 3.109\% 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. O=C(c1ccc(O)cc1)c1ccc(C(=O)c2ccc(O)cc2)cc1
b. O=C(O)C1CCCCC1C(=O)Nc1nccs1
c. Cc1ccccc1Cn1cc(NC(=O)c2nc3ncccn3n2)cn1
d. COc1cc(CC(=O)Nc2sccc2C(N)=O)cc(OC)c1OC
Answer: a. O=C(c1ccc(O)cc1)c1ccc(C(=O)c2ccc(O)cc2)cc1
