D)Li+ and H-

C) is the correct answer
  • 4
The correct answer is option B.
  • -2
A is the correct answer
  • -1
Correct answer is b
  • 9
Size of H is very much larger than Clor o− due to very less Zeff​ in H, it's outer electron are free to maximise the radii. So, H- has a greater radius than even F-. So, the correct answer is (B)
