Which sentence is the correct one?

এখানে since Friday – point of time থাকার কারণে Present Perfect Continuous Tense হওয়ার কথা।
কিন্তু মূল Verb – be verb হলে Present Perfect Continuous এর পরিবর্তে Present Perfect Tense হয়।
তাই correct sentence: He has been ill since Friday.

অন্যান্য sentence গুলোর সঠিক রূপ:
- The train has just left. (just থাকায় Present Perfect Tense হবে)
- The house was built by her husband last month. (last month- অতীতের সময় উল্লেখ থাকায় এটি Past Indefinite Tense হবে।)
- His grandfather died in 2009. (in 2009 - অতীতের সময় উল্লেখ থাকায় এটি Past Indefinite Tense হবে।)
