Answer 1

Hint: An assertion means the forceful or the confident statement or it may be fact and belief whereas the reason is an explanation about that particular statement. First we will find if the given assertion is true or false and then will decide whether the given assertion and the reason are correct or not.

Complete step by step answer:
Given that - In a movie, ordinarily $24$ frames are projected per second from one end to the other of the complete film.
But in actuality the image formed on the retina can sustain up to $\dfrac{1}{6}$ second after the removal of the stimulus.
Therefore, the given reason is not correct.
Assertion is true but reason is false.

So, the correct answer is “Option C”.

Note:
Always judge each given statement of the assertion and the reason independently. If you are able to find out the incorrect statement, then you have solved the statement and accordingly determine whether the given statements are true or false. These types of questions are generally asked in the competitive exams.
