A proton moves in a region of constant electric field. Does it follow that the proton’s velocity is parallel t?

Only if there are no other forces affecting the proton.
There could be gravity, but the effect of Earth's gravity is negligible on a proton compared to anything but the tiniest electric field. We could say for all practical purposes the acceleration of the proton is still parallel to the electric field.
There could be magnetism. If there is a magnetic field, it will apply a force perpendicular to the proton's velocity. That might or might not be parallel to the electric field. Magnetism can easily have an affect on a proton similar in order of magnitude to an electric field.
We could talk about the strong force and the weak force, but it would be a bit silly. Common sense would suggest the question is asking about a free proton, not part of any nucleus. With no other nuclear particles nearby the strong force and weak force, which have limited range, would not have any significant effect.
it can't ensure in an area the place there is not any electric powered container and if the electron travels with consistent velocity, the magnetic container is 0. because of the fact whether magnetic container is present day and if theta = 0 or one hundred eighty tiers, the tension on the electron is F = B e v sin(0) or B e v sin(one hundred eighty) = 0 and the electron retains on moving with consistent velocity.
