If the following segments of a sentence are to be rearranged in logical order as A, B, C, D where would ‘3’ be placed
1) to see that students do not altogether forget to write especially during exam time
2) the education groups are now asking for hand writing classes
3) thanks to mobile testing and computer literacy
4) writing in long hand is becoming a vanishing art

Writing in long hand is becoming a vanishing art thanks to mobile testing and computer literacy. The education groups are now asking for hand writing classes to see that students do not altogether forget to write especially during exam time.

The above gives the correct ordering of the sentences. We can see that the third sentence, comes in the second part of the sentence. Hence, option B is the correct answer.
