Answer:
b. Its horizontal velocity component is the same as it was just as it was launched
Explanation:
When the rock is thrown from the upper edge of the cliff, at some angle with the horizontal. There is no any acceleration in horizontal direction, therefore, the horizontal velocity remains the same, whereas there is a constant downward acceleration of the magnitude g= 9.81 m/s^2. This causes the increase in vertical velocity of the rock in downward direction.
therefore true statement just before it hits the ground
b. Its horizontal velocity component is the same as it was just as it was launched.
