Best answer
Right option is (b) Collecting a SAGE library is quite economical

The best I can explain: The Gene identification from SAGE data is also more cumbersome because the mRNA tags have to be extracted, compiled, and identified computationally, whereas in DNA microarrays, the identities of the probes are already known. In SAGE, comparison of gene expression profiles to discover differentially expressed genes and co-expressed genes is performed manually, whereas for microarrays, there are a large number of software algorithms to automate the process.
