Option 1 suggests that Bhaskaracharya computed the time taken by the Earth to orbit the Sun, Gyandev calculated the value of `pi`, Aryabhatta invented digit zero, and Budhayana created the game of snakes and ladders.

Option 2 proposes that Aryabhatta computed the time taken by the Earth to orbit the Sun, Budhayana calculated the value of `pi`, Bhaskaracharya invented digit zero, and Gyandev created the game of snakes and ladders.

Option 3, which is also the correct answer, aligns the contributions properly. It states that Bhaskaracharya computed the time taken by the Earth to orbit the Sun, Budhayana calculated the value of `pi`, Aryabhatta invented digit zero, and Gyandev created the game of snakes and ladders.

Option 4 presumes that Aryabhatta computed the time taken by the Earth to orbit the Sun, Gyandev calculated the value of `pi`, Bhaskaracharya invented digit zero, and Budhayana created the game of snakes and ladders.

The right match of scholarly contributions prominently positions key improvements of the four Ancient Indian scholars.
