Answer: d. smaller.
Explanation:
Hybridization :
N = number of electrons
where, V = number of valence electrons present in central atom i.e. oxygen = 6
N = number of monovalent atoms bonded to central atom=32
C = charge of cation = 0
A = charge of anion = 0
The number of electrons is 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral. The bond angle for tetrahedral geometry is
But as there are two atoms around the central oxygen, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent and the bond angle will be smaller than expected and is

Answer:
Elliptical galaxies are one of the three types of galaxies. They have a rounded shape of an ellipse, like a stretched-out circle. They lack the swirling arms that are a main feature of spiral galaxies.
