Explanation:

Correct Option -1 :  'BCAD'.
The given sentence is an example of a Para Jumble.
We know that the first statement of a para jumbled question is usually an independent general statement, a noun, a universal fact, starting of an incident, or it starts with 'most' or 'once'.
• Sentence B in the given question is the starting of an incident. It talks about the
author meeting his grandmother after a long while.
• Sentence C will be the next sentence because when the author went to meet his grandmother, he saw her standing at the village bus stand to receive him.
• Sentence A will be the next sentence because it explains the expressions on the face of the author's grandmother when he saw her standing at the village bus stand to receive him. Lastly, Sentence D will be used because it expresses what her grandmother did when she received him.
• Thus, the sequence becomes:
 B: It was quite a long time since I had met my grandmother.
C: I found her standing at the village bus stand to receive me. o A: She looked very excited when she saw me get off the bus. • D: She hugged me and tears of joy flowed down her cheeks.
• Therefore, as per the points mentioned above, we find that the correct answer is Option 1.

Correct Sequence: It was quite a long time since I had met my grandmother. I found her standing at the village bus stand to receive me. She looked very excited when she saw me get off the bus. She hugged me and tears of joy flowed down her cheeks.
