A proton is initially moving at high speed

so here initially proton is having high speed and high kinetic energy
now this proton comes to rest by external electric field
so the potential energy of proton will increase or we can say that kinetic energy will convert into electrostatic potential energy
so here the proton must have to move at higher potential region
so here correct answer must be
b. Because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.
Answer: A cold front occurs when cold, denser air replaces the rising, less dense air mass. The reason this front brings in the rain is that as the rising warm air cools (as it rises to the cooler upper atmosphere) the moisture in it condenses into clouds that precipitate down as rain or snow.
