Answer:
A. from low to high potential
Step-by-step explanation:
When positive charge is released in constant uniform field then it will always move in the direction of electric field
while negative charge always moves in the opposite direction of electric field
now we also know the relation between potential difference and electric field as
so we can say in the direction of electric field potential always decreases
so when positive charge is released in electric field then it moves from higher potential to lower potential while when negative charge is released then it will move from lower potential to higher potential
So correct answer is
A. from low to high potential
