26-30 Direction
Read the passage given below:

What is discipline? Is it absolute freedom to do what a person wants? Is freedom regardless of consequences? Does it mean corrective action after a problem occurs or a wrong is done? Is it imposition? Is it abuse? Does it take away freedom?
The answer is none of the above. Discipline does not mean that a person takes a belt and beats up kids. That is madness. Discipline is loving firmness. It is direction. It is prevention before a problem arises. It is harnessing and channeling energy for a great performance. Discipline is not something you do to yourself but you do for those you care about.
Discipline is an act of love. sometimes, you have to be unkind to be kind. Not all medicines are sweet, not all surgeries are painless, but we have to take them. We need to learn from nature. We are all familiar with the big animal, the giraffe, A female giraffe gives birth to a baby giraffe standing. All of a sudden, the baby falls on the ground from the cushion of its mother’s womb and sits on the ground. The first thing the mother giraffe does is get behind the baby and give it a hard kick. The baby gets up but sits down again. The mother keeps kicking till the baby gets up on its feet and starts moving. Why? Because she knows that the only chance of survival for the baby in the jungle is to be on its feet. Otherwise, it will be eaten up by wild cats. Children brought up in a loving yet disciplined environment end up respecting their parents more and become law-abiding citizens. The reverse is just as true. Good parents are not afraid of momentary dislike by children to enforce the subject. Allowing a child to eat a box of chocolate could lead to sickness. At the same time, the discipline of eating one or two pieces a day can be an enjoyable experience for a longer time. Our instinct makes us do whatever we want regardless of consequences. Freedom is not procured by the full enjoyment of what is desired but by the controlling of desire.

On the basis of your understanding of the passage, answer the questions by choosing the correct options:
