Answer 1

Explanation:

ANSWER:-

Let us understand what is Handpicking.

As the name suggests, Handpicking is the method of separating things by hand.

Common Example:-

We often see people separating small stones from Puffed Rice or other pulses.

Now, considering the statements:-

Statement I: Substances X and Y are exactly of same size.

If both are of same size, won't it create a confusion?

So, Statement 1 cancelled.

Statement II: Substances X and Y are visible and accessible with hands.

Correct Statement.

Statement III: Substances X and Y look different from each other.

Of course, if they are not different, why would we not like to separate then off?

Of course we would not like to separate Rice from Rice, that's obvious!

So, That's correct.

And the final answer is (D) Both II and III.
