Which sentence is the correct one?

সবগুলোর সঠিক বাক্য হবে:
• 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।)
• He has recently launched a new business. (recently থাকলে Present Perfect Tense হয়, এবং এখানে যথাযথভাবেই তা আছে)
• His grandfather died in 2009. (in 2009 - অতীতের সময় উল্লেখ থাকায় এটি Past Indefinite Tense হবে।)
