MCQ
For two statements are given $-$ one labelled Assertion $(A)$ and the other labelled Reason $(R).$ Select the correct answer to these questions from the codes $\ce{(a), (b), (c)}$ and $(d)$ as given below :
Assertion : Multiple fission produces many daughter cells simultaneously.
Reason : Multiple fission occurs during favourable conditions.
  • A
    Both $A$ and $R$ are true and $R$ is correct explanation of the assertion.
  • B
    Both $A$ and $R$ are true but $R$ is not the correct explanation of the assertion.
  • ✓
    $A$ is true but $R$ is false.
  • D
    $A$ is false but $R$ is true.
✓

Answer

Correct option: C.
$A$ is true but $R$ is false.
In multiple fission, the parent organism divides into many daughter cells at the same time during unfavourable conditions like deficiency of food or water and extremes of temperature. Production of large number of daughters increases the chances of survival of daughter cells.
