Thanks for explaining @Ganeshr.

here you can make 6 binary joints i.e
(1"2) link 'Binary Joint
(1"3) link 'Binary Joint
(1"4) link 'Binary Joint
(2"3) link 'Binary Joint
(2"4) link 'Binary Joint
(3"4) link 'Binary Joint.
Similarly here if we select any three binary joints{for eg: (1"2),(1"3),(1"4)} the other three will appear automatically{i.e (2"3),(2"4),(3"4)} because they are Dependent.
Thus, 1 QuaternaryJoint = 3 Binary Joint.
So, the Given answer is correct.
(1"2) link 'Binary Joint
(1"3) link 'Binary Joint
(1"4) link 'Binary Joint
(2"3) link 'Binary Joint
(2"4) link 'Binary Joint
(3"4) link 'Binary Joint.
