Given \[\theta =\] angle through which the axis of the outer forward wheel turns

\[\phi =\]Angle through which the axis of the inner forward wheel turns

a = distance between the pivots of front axle and

b = wheel base

For correct steering, centre lines of the axes of four wheels of an automobile should meet at a common point. This condition will be satisfied if:

A) \[\cos \theta -\cos \phi =\frac{a}{b}\]      

B) \[\cot \theta -\cot \phi =\frac{a}{b}\]

C) \[\cos \theta +\cos \phi =\frac{a}{b}\]     

D) \[tan\theta +tan\phi =\frac{b}{a}\]
