Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.970\% 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] O=C(Nc1ccc2nc(-c3ccccn3)c(-c3ccccn3)nc2c1)N1CCOCC1
[b] O=S(=O)(c1cccs1)N1CCN(c2ccc(O)cc2)CC1
[c] CCOC(=O)c1c(CN2CCOCC2)oc2ccc(OC)cc12
Answer: c. CCOC(=O)c1c(CN2CCOCC2)oc2ccc(OC)cc12
