hello friend...!!!
⇒ the answer is option ' A '
⇒ the given expression is a unit vector
⇒ it is because , the magnitude is = 1
⇒ √ x² + y² = √ ( 1/√2)² + ( 1/√2)²
⇒ √ 1/ 2 + 1 / 2 = √ 2 / 2 = √ 1 = 1 .
since the magnitude is equal to 1 therefore it is a unit vector.

hope it helps...!!

Hey, here is your answer....
It's option A...
BECOZ,
Given expression: [1/√2 i +1/√2 j]....
So, we need to find the magnitude of that expression..... then,
[{(1/√2)^2 + (1/√2)^2}]^1/2...
[{(1/2) + (1/2)}]^1/2....
[{1}]^1/2.....
√1... = 1....[this is the magnitude]....
so, it's a unit vector....[since, the magnitude is 1]...
hope this helps you....
plzzz mark it as brainliest.....
