1 : Paintings P : have been Q : which were submitted R : totally ruined by rain S : for the exhibition 6 : last night. The Proper sequence should be:

The correct answer is: PQRS

The sentence is about paintings that were submitted for an exhibition and were ruined by rain last night. The correct order of the words is:

1. Paintings
2. which were submitted
3. for the exhibition
4. last night
5. have been
6. totally ruined by rain

The sentence can be rearranged as follows:

Paintings which were submitted for the exhibition last night have been totally ruined by rain.

The other options are incorrect because they do not follow the correct order of the words. For example, in option B, the word “ruined” comes before the word “submitted.” This is not the correct order of the words, because the paintings were submitted before they were ruined.

In option C, the word “ruined” comes after the word “exhibition.” This is also not the correct order of the words, because the paintings were ruined before they were exhibited.

In option D, the word “ruined” comes after the word “rain.” This is also not the correct order of the words, because the paintings were ruined by the rain.
