[A]. (R - S) tan θ/2 - L/2
[B]. (R + S) tan θ/2 - L/2
[C]. (R + S) tan θ/2 + L/2
[D]. (R - S) tan θ/2 + L/2
[E]. (R - S) cos θ/2 + L/2

R = Radius of main curve.
S =Shift.
L = Length of Transition curve.
θ = Angel of Deflection.

(Radius + Shift ) tan θ /2 + L/2.

@Shubham V.

Shift is difference between line of transition curve and circular curve.
