Answer 1

\huge\frak\pink{answer}

The coordinates of the given points are (a,b) and (0,0) and the distance between them is d.

By distance formula,

d=(a−0)2+(b−0)2

∴d=a2+b2

Option A: d=(−23)2+(−23)2=23=232

Option B: d=(−1)2+(−1)2=2

Option C: d=(−21)2+02=21

Option D: d=02+12=1

Hence, d is greateat when (a,b) is
