D
Explanation:  D) This question tests understanding of the idea that cDNAs are derived from mRNAs, making the choice of tissue critical for isolation of a particular gene. In contrast, the choice of tissue makes no difference for genomic libraries since all cells contain the same set of genes (with rare exceptions, e.g. certain blood cells).
