C is correct because the Lag distance is the distance travelled during perception time and brake reaction time (before application of brake).

Lag distance is defined as distance travelled by vehicle during the reaction time of driver. i.e, (Reaction time is a combination of perception time and brake reaction time).

The given answer is correct.

t=2.5 sec is the total reaction time of the driver in second depending on the PIEV condition only and not related with the break or on its efficiency or timing.
And also the question is asking about the distance travelled by vehicle both perception & break reaction time, and lag distance hasn't any relation with a break.
Thus option B must have to be the correct answer.

C is the right answer because 2.5 sec is the perception and reaction time(t).
And SSD = V * t + V^2/2gf.
In which V * t is lag distances.
And SSD = V * t + V^2/2gf.
In which V * t is lag distances.

Stoping is correct.

Thank you @Kabiraj.

Stoping distence=lag distance+break distance.
lag----The distance travelling by a moving vehicle during perception and break reaction time. Break distance---the distance travelling by amoving vehicle after break reaction time to stop.

I also think the answer B.
Please explain it clearly.
