Hi - I understand why D is the right answer but i do have a query on A/B/ E
In A / B / E -- is it possible to eliminate based on tenses as mentioned in some of the analysis above ? if so, could someone elaborate as i dont know the theory why ...specifically i have marked in bold if based on these alone, i can eliminate answer choices
