D is the correct answer since all others are highly unlikely.
Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

Answer:
66.7m/s²
Explanation:
initial velocity(V)=54m/s
Final velocity(U)=4m/s²
Time taken(t)= 0.75 seconds
Acceleration is unknown
To find the acceleration we use this formula
a=v-u/t
a=54-4/0.75
a=50/0.75
a=66.666666
since it is acceleration we use the symbol m/s² after approximating to 1 decimal place
a=66.7m/s²
