A
Maximum speed of the particle is $4$ units.
✓
Particle further comes to rest at $x = 4.$
C
Particle oscillates about $x = 2.$
D
Particle will continuously accelerate along the $x-$axis.

✓

Answer

Correct option: B.

Particle further comes to rest at $x = 4.$

$b.$ Particle further comes to rest at $x = 4.$
$c.$ Particle oscillates about $x = 2.$
