The correct sequence is Option 3, i.e. 'BCDA'.

The first sentence of the sequence is the one, which introduces the paragraph. The one that fits here is 'Sentence B' as it tells about the subject of the paragraph on, which the whole paragraph is based. 

It tells about 'Patience', which is a virtue and considered to be even better than wisdom'.

Then the second sentence of the sequence is the one, which adds information to the introductory sentence of the paragraph and the one that follows is 'Sentence C', i.e. 'Everyone of us AGREES with this fact in principle, without reservation'. 

It says that 'everyone of us agree about the fact that what is 'Patience' and how much it is considered'.

Next, the sentence, which MAKES a PAIR with 'Sentence C', and the one that follows is 'Sentence D', it says that unfortunately when it COMES to practising patience, there is a problem. It follows the Sentence C by adding more information to it.

At last the sentence, which is left in the sequence is the concluding sentence of the paragraph.

The sentence is 'Sentence A', it concludes the paragraph by mentioning that 'Nobody likes to practice it, no matter how easy and beneficial it is.This is the worst drawback in us, in our NATIONAL character'.
