Question

Choose the correct option.

If 'inter' means between as in interstate, 'intra' as in intravenous means _________.

• A. into
• B. onto
• C. within
• D. without

Hint:

Compare intra with inter: inter links separate things, intra stays inside one thing.

Answer 1

The Correct Option is C

Step 1: Look at the prefix 'inter'.
The word interstate uses 'inter', and it means between two or more states. So 'inter' shows a link between separate things.

Step 2: Look at the prefix 'intra'.
'Intra' works in the opposite way to 'inter'. It does not point to a link between separate things, it points to something happening inside one single thing.

Step 3: Apply this to 'intravenous'.
Intravenous means given or taking place inside a vein. A drip or injection that goes intravenous goes directly within the vein, not between veins.

Step 4: Match this meaning to the options.
"into" suggests movement toward the inside from outside, which is close but not exact. "onto" means on top of a surface, which does not fit a vein at all. "without" means the opposite, outside or lacking. "within" means inside the boundary of something, and this matches intra exactly.

Final Answer:
'Intra' means within, so option 3 is correct. \[ \boxed{\text{within}} \]
