Step 1: What “original form” means.
It refers to the Constitution {as it came into force in 1950}, before later amendments altered the count.
Step 2: The original structure.
At commencement, the Constitution had 395 Articles, 22 Parts and 8 Schedules. The current count (after many amendments) is higher, which explains the distractor \((D)\,448\).
Step 3: Conclude.
\[
\boxed{\text{395 Articles (Option B) in the original Constitution.}}
