In the arrangement shown in figure \( a_{1}, a_{2}, a_{3} \) and \( a_{4} \) are the accelerations of masses \( m_{1}, m_{2}, m_{3} \) and \( m_{4} \) respectively. Which of the following relation is true for this arrangement?
(a) \( 4 a_{1}+2 a_{2}+a_{3}+a_{4}=0 \)
(b) \( a_{1}+4 a_{2}+3 a_{3}+a_{4}=0 \)
(c) \( a_{1}+4 a_{2}+3 a_{3}+2 a_{4}=0 \)
(d) \( 2 a_{1}+2 a_{2}+3 a_{3}+a_{4}=0 \)
