Answer:

B

Step-by-step explanation:

Noting the following rule of radicals

\sqrt{a} × \sqrt{b} = \sqrt{ab}

Given

(\sqrt{2} + \sqrt{3})( \sqrt{5} - \sqrt{7} )

Each term in the second factor is multiplied by each term in the first factor

= \sqrt{2}(\sqrt{5} - \sqrt{7}) + \sqrt{3}(\sqrt{5} - \sqrt{7}) ← distribute parenthesis

= \sqrt{10} - \sqrt{14} + \sqrt{15} - \sqrt{21}
