A. Machine Language
B. None of these
C. Assembly Language
D. Object code
🧠 Explanation:
The first computers were programmed using machine language, a low-level code of binary instructions (0s and 1s) directly understood by hardware. Unlike modern high-level languages, it was complex and error-prone but foundational for computing. Machine language enabled early automation, shaping modern programming. Studying it provides insights into computing history, software development, and technological evolution, a key topic in computer science, highlighting the roots of coding and its impact on today’s digital systems and applications.
