Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.563\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1cccc(N2CCN(C(=O)CCCCCNc3nc(=S)[nH]c4ccccc34)CC2)c1
[b] O=C(O)c1ccc2c(c1)OCCCO2
[c] COc1cc(N2Cc3ccccc3C2)ccc1C=O
Answer: b. O=C(O)c1ccc2c(c1)OCCCO2
