Chemical shift values depends on the electronic nature around the hydrogen atom. If that electronic nature is same then their chemical shifts will be same.
Option A is wrong as chemically equivalent proton may be at low field or down field depending on the electronic nature around hydrogen s.
Option. B is also wrong all the spins are in same direction.
Option C is wrong as those hydrogens are split by the adjacent hydrogens . Option D is correct.
