hi...

time<2 hrs and is speed >60..

these details itself will get you to the correct option..
Since we do not know the exact time, lets takt at just equal to 2 hrs. so for 60km/hr, it should travel equal or more than 60*2=120
this actually gets you to B and thus B is sufficient..

but lets see the statements..
(I) distance <125..
if D is 124 speed <124/2 or >62 ...ans YES
if D is 2 km, speed <2/1 or 1...ans NO
insuff

(II)
D>122..
so MIN speed = 122/2=61
ans is always YES irrespective of T

suff

B
