Two identical blocks A and B, each of mass `m=3kg`, are connected with the help of an ideal spring and placed on a smooth horizontal surface as shown in Fig. Another identical blocks C moving velocity `v_0=0.6(m)/(s)` collides with A and sticks to it, as a result, the motion of system takes place in some way
Based on this information answer the following questions:
Q. After the collision of C and A, the combined body and block B would

Option1
oscillate about centre of mass of system and centre of mass is at rest.
Option2
oscillate about centre of mass of system and centre of mass is moving.
Option3
oscillate but about different location other than the centre of mass.
Option4
not oscillate.

b) Components of embryo sac-After positive pollen pistil interaction, the pollen tube develops and enters the ovule through synergids guided by flliform apparalus.
1. One of the male gamete fertillses the female gamete to form diploid zygote.
2. The other male gamete fuses with the secondary nucleus (Polar nuclei if they are already formed) to form a triploid primary endosperm nucleus (PEN) which forms endosperm.
3. The three antipodals at chalazal end and synergids at micropylar end start degenerating.
