Option (2) 
 
A body thrown vertically upwards with velocity u reaches height h after T seconds then at a time 2T it will reach ground with same velocity but in opposite direction (directed down)  i.e. -u 
Negative sign indicates the opposite direction of falling body with same velocity u 
Option (3)
