Answer: Option B

Explanation:

Source Code: উৎস প্রোগ্রাম, যা একজন প্রোগ্রামার দ্বারা লিখিত একটি কোড। সাধারণত একটি উচ্চ স্তরের ভাষা ব্যবহার করে, যা মানুষের দ্বারা সহজেই পাঠযোগ্য।

Object Code: অবজেক্ট প্রোগ্রাম সাধারণত একটি মেশিন এক্সিকিউটেবল ফাইল, যা একটি কম্পাইলার ব্যবহার করে উৎস ফাইল কম্পাইল করার ফলাফল। যেহেতু তারা মেশিন কোডে নির্দেশাবলী রাখে, তাই তারা মানুষের দ্বারা সহজেই পঠনযোগ্য নয়।

Executable File: এটি হল Object Code কে linking নামক প্রক্রিয়ার ভিতর দিয়ে চালনা করার ফলাফল। এটি এমন মেশিন কোড, যা সরাসরি মেশিন (সিপিইউ )দ্বারা চালিত হতে পারে।

Source Code > Object Code > Executable File > Machine(CPU)

অর্থাৎ Object Code ও Executable File উভয়ই machine ল্যাংগুয়েজে লেখা তবে এদের ভিতর Executable File সরাসরি মেশিন (সিপিইউ )দ্বারা চালিত হতে পারে। Object Code লিংকিং নামক প্রসেসের দ্বারা Executable File এ পরিণত হয়।
