If two non-parallel vectors \overrightarrow a and \overrightarrow b are equal in magnitude, then the vectors (\overrightarrow{ a} - \overrightarrow b) and (\overrightarrow a + \overrightarrow b) will be: (A) parallel to each other (B) perpendicular to each other (C) anti-parallel to each other (D) inclined at an angle less than 90^{
