☆Actually welcome to the concept of Vectors and its application and unit vector...

☆Basically we know that a unit vector along its direction is given as .....

☆Unit vector = the vector divided by its own magnitude .....

☆thus U cap = U vector / Modulus of U .....

☆since here the vector is xi + yj....then the unit vector will be ....

☆xi + yj / square root of x^2 + y^2 ......

☆ since we know that i^2 and j^2 will be 1.....

☆thus the option will be C.) .
