Answer:

[tex]\frac{3}{7}.v[/tex]    option (C) is correct

Step-by-step explanation:

projection of vectors: The vector projection of one vector over another vector is the length of the shadow of the given vector over another vector.

projection of vector u on v is given by :

[tex](\frac{u.v}{v.v}).v[/tex]

Given,

vector u = <5, 7, 1>

vector v = <2, -1, 3>

substituting these values in the above formula

[tex][\frac{(2,-1,3)(5,7,1)}{(2,-1,3).(2,-1,3)} ].v[/tex]  =  [tex]\frac{6}{14}.v= \frac{3}{7}.v[/tex]

thus the correct answer is option (C)
