(D) The Assertion is incorrect because $mRNA$ attaches to the ribosome at the $5'$ end,specifically at the Shine-Dalgarno sequence in prokaryotes or the $5'$ cap in eukaryotes,not the $3'$ end.The Reason is also incorrect as there is no such thing as an '$F-$ capsular nucleotide' in $mRNA$ structure.Therefore,both the Assertion and the Reason are incorrect.
