In a species,the weight of newborn ranges from 2 to 5 kg. 97% of the newborn with an average reight between 3 to 3.3 kg survive whereas 99% of the infants born with weight from 2 to 2.5 kg or 4.5 to 5 kg die.Which type of selection process is taking place ?
Directional Selection
Stabilizing Selection
Disruptive Solution
Cyclical Solution
Directional selection
2 )stabilizing selection will be the correct answer as in this case the mid characters are favoured not the extremes

Stabilizing or balancing selection -
A type of natural detection which leads to the elimination of organism having over specialised characters and maintains homogeneous population which is generally constant.
- wherein
It favours the average or normal phenotypes. Results in very low rate of evolution.
Stabilizing selection favours the medium types
while the extreme phenotypes 
are eliminated.
