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 : Stock is the lower part of a plant having the roots.
Reason : In grafting, the stock is placed over the scion.
  • 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.
Grafting is a method in which the cut stems of two different plants $($one with roots and other without roots$)$ are joined together in such a way that the two stems join and grow as a single plant. Stock is the lower part of a plant $($or tree$)$ having the roots. Scion is the upper part of a plant which may have leaves on it $($but no roots$).$

Assertion (A): A proton moves horizontally towards a vertical long conductor having an upward electric current. It will deflect vertically downward.
Reason (R): Seeing the proton and the conductor from the side of the proton, the magnetic field at the site of the
proton will be towards the right. Hence the force $\vec{F}=q \vec{\nu} \times \vec{B}$ will deflect the proton vertically downward.
