(D) The correct answer is $(d)$.Transcription is the process in living cells in which the genetic information of $DNA$ is transferred to $mRNA$,not $tRNA$,as the first step of gene expression.An operon consists of structural genes,a promoter,an operator,and a regulator gene. Therefore,the definition in $(c)$ is incomplete as it omits the regulator gene.Since both $(a)$ and $(c)$ are incorrectly matched,$(d)$ is the correct choice.
