Answer:
The correct answer would be acrylic glass.
It can be explained with the help of refractive index.
It is a dimensionless number used to describe that how fast a light can propagate through a material.
Thus, the more the refractive index the more will be the bending.
Acrylic glass has the least refractive index as compared to the other materials provided.
Thus, the light would bend the least if acrylic glass would be used.
Answer: Option A.
Achondrogenesis
Explanation:
Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia are conditions of Achondrogenesis because
