What is the unknown compound based on the IR Spectrum, explain why or the others are not the compound

A.) How many signals does the HNMR of the unknown C6H14O have? B.)Whats the ratio between the number of different hydrogens in the unknown compound C6H14O? C.)Explain splitting patterns of all the signals (in depth if possible the lecture confused me). D.)Explain the chemical shifts of the signals based upon the locations of hydrogens relative to the desheilding groups if any are present in the compound.   For A. I think there are 4 signals. For B. I think the ratio is 1:1:3:9 for the hydrogens on the HNMR spectrum. For the last 2 questions (C. and D.) the lecture confused me so an in depth of how you found the answer would be greatly appreciated. Also the unknown for the attached HNMR is C6H14O.

The question asks how many H signals would we expect to see in the H NMR spectrum. My question is why is the Hydrogen indicated by the arrow any different from the other 2 in circled in red nearby? Does it have to do with it being farthest from the Br?

A total of how many signals are expected in the ¹H spectrum of the given compound? CI о

Provide the structure or SMILES of the compound with molecular formula C8H8O and correlates with the NMR shown in the image
