Arrange $NH_4^ + ,\,{H_2}O,\,{H_3}{O^ + },\,HF$ and $O{H^ - }$ in increasing order of acidic nature

• A
  ${H_3}{O^ + } < NH_4^ + < HF < O{H^ - } < {H_2}O$
• B
  $NH_4^ + < HF < {H_3}{O^ + } < {H_2}O < O{H^ - }$
• ✓
  $O{H^ - } < {H_2}O < NH_4^ + < HF < {H_3}{O^ + }$
• D
  ${H_3}{O^ + } > HF > {H_2}O > NH_4^ + > O{H^ - }$
