How can can I make the page B to render like page A (which tool/method should be used)?
The issue with this particular PDF is that it is only 4 inches wide and you are reading it on a reader with an 8.25-inch wide screen. You can use k2pdfopt to create a new PDF where the source PDF is magnified to fit the width of an 8.25-inch page using the settings in the attached screen shot, or the command below.

k2pdfopt -w 8.25in -h 11in -odpi 200 -ds 2.5 -fc- -mode fw -ls- pages.pdf

The -ds 2.5 increases the size of the source document by 2.5x so that it effectively becomes 10-inches wide. The "-mode fw" then fits that text to the specified reader screen width of 8.25 inches. I've attached the result.
