$\huge{\underline{\underline{\mathsf{\purple{Solution}}}}}$

${\boxed{\mathtt{\green{GIVEN}}}}$

1. ${\mathsf{\pink{A \:scored\: higher\: than \:B}}}$

2. ${\mathsf{\pink{G \:scored\: higher\: than\: A }}}$

3. ${\mathsf{\pink{Either\: D \:scored \:highest\: rank\: and\: B \:/ \:F \:got \:least\: marks}}}$

4. ${\mathsf{\pink{Or\: C\: scored \:highest \:and\: E\: scored \:least}}}$

5.${\mathsf{\pink{G \:scored\: Fifth\: rank}}}$

___________________

Now we are given that A scored higher than B so

→ A > B

G scored higher than A and if G us higher than A then it's definitely higher than B .

→ G > A > B

Now Rank of G is 5th . So ,

→ Rank of A = 6th

→ Rank of B = 7th .

There are total 7 candidates .

Hence B scored the least rank .

Now it's given in point 3rd that If B or F will score least then D will score the highest.

So in the option given below option B is Correct .

$\huge{\boxed{\mathsf{D\:will\:score\: the\: highest\:rank}}}$
