The incorrect statement$(s)$ regarding $\overset{\bullet }{C}X_{3}$ species is:

• A
  If electronegativity of surrounding element $'X'$ is less than $2.5,$ then central carbon atom uses almost $33\% \ s-$character in its hybrid bonding orbitals.
• B
  If electronegativity of surrounding element $'X'$ is greater than $2.5,$ then central carbon atom uses almost $25\% \ s-$character in its hybrid bonding orbitals.
• C
  If $'X'$ is $'F'$,then the species should be polar and pyramidal.
• D
  If $'X'$ is $H,$ then the species should be polar and planar.
