MCQ

If the ionic radii of $K^+$ and $F^-$ are nearly the same (i.e., $1.34\, \overset{o}{\mathop{A}}\,)$, then the atomic radii of $K$ and $F$ respectively are

A
$1.34 \,\overset{o}{\mathop{A}}\,, 1.34\, \overset{o}{\mathop{A}}\,$
B
$0.72 \,\overset{o}{\mathop{A}}\,, 1.96\, \overset{o}{\mathop{A}}\,$
✓
$1.96\, \overset{o}{\mathop{A}}\,, 0.72\, \overset{o}{\mathop{A}}\,$
