The correct option is (D) Gamma ( 
)
Explanation:
Now this question is a tricky one because all of these options are somehow involved in radioactive decay; however, in this case the SYMBOL is required NOT the elements. There are three symbols involved in radioactive decay, which are:
1. α for alpha decay
2. β for beta decay
3. γ for gamma decay
In the options only one symbol is present which is gamma. Hence option (D) Gamma ( ) is the correct answer.

Answer:
The value is
Explanation:
From the question we are told that
The diameter of each wheel is
The mass of the motorcycle is
The rotational kinetic inertia is
The mass of the rider is
The velocity is
Generally the radius of the wheel is mathematically represented as
=>
=>
Generally from the law of energy conservation
Potential energy attained by system(motorcycle and rider ) = Kinetic energy of the system + rotational kinetic energy of both wheels of the motorcycle
=>
=>
Here is the angular velocity which is mathematically represented as
So
Here
=>
