As, escape velocity
so its value depends on mass of planet and radius of the planet. The two different planets have same escape velocity, when these quantities (mass and radius) are equal.

Read the assertion and reason carefully to mark the correct option ou...
Assertion: Two different planets have the same escape velocity.
Reason: The value of escape velocity is a universal constant.
The correct answer is option D: If the assertion and reason both are false.
Explanation:
The assertion and reason given in the question are both incorrect. Therefore, the correct answer is option D.
Explanation of the Assertion:
The assertion states that two different planets have the same escape velocity. However, this statement is incorrect. The escape velocity of a planet is a unique value determined by its mass and radius. It represents the minimum velocity an object must have to escape the gravitational pull of the planet. Different planets have different masses and radii, resulting in different escape velocities. Therefore, it is not possible for two different planets to have the same escape velocity.
Explanation of the Reason:
The reason given in the question states that the value of escape velocity is a universal constant. This statement is also incorrect. The escape velocity of a planet is not a universal constant but depends on the specific characteristics of that planet. As mentioned earlier, the escape velocity is determined by the mass and radius of the planet. Therefore, different planets will have different escape velocities.
Conclusion:
In conclusion, the given assertion and reason are both incorrect. The escape velocity of a planet is not a universal constant, and two different planets cannot have the same escape velocity. Hence, the correct answer is option D: If the assertion and reason both are false.
