well we can say that ans d is correct because emu has both the features mentioned in the question while option b describes only one of them

Ans 50:

Class : Class 6
the answer is B

Ans 51:

Class : Class 4
The answer is d because they ask which is " INCORRECT", AND OPTION B IS THE CORRECT OPTION, AND BOTH A AND C ARE INCORRECT. AS THEY HAVE ASKED INCORRECTLY, THE ANSWER IS D, AS BOTH A AND C ARE WRONG.

Ans 52:

Class : Class 3
Bats have wings and no feathers. Ostriches and Emus have both feathers and wings, but they can’t fly mainly due to their huge size. Penguins have feathers and flippers (not wings). “A” is incorrect as bats doesn’t have feathers. “B” is incorrect as penguins doesn’t have wings. “C” is incorrect as there are birds that has both feathers and wings. “D” is the correct answer

Class :
oil has a low boiling point than water. Therefore we use oil to make the cooking process faster and easier

Ans 2:

Class :
We fry stuff in oil because oil has much higher boiling point in comparison to water. So after heating when oil reaches temperatures greater than the boiling point of water (100 C) it instantly vaporize the water present in food into steam. ... Oil fries it and gives a crispy texture.
