Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.644\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COc1ccc(C2CC(c3ccccc3)=NN2C(=O)CSc2ncn[nH]2)cc1
b O=C(N1CCOCC1)N1CCN(c2ccccc2)CC1
c O=C(COC(=O)c1n[nH]c2ccccc12)NC(=O)NCc1ccco1
Answer: b. O=C(N1CCOCC1)N1CCN(c2ccccc2)CC1
