Although the geometries of NH 3 and H 2 O molecules are distorted tetrahedral, why is the bond angle in water less than that of ammonia?

Question

Although the geometries of NH 3 and H 2 O molecules are distorted tetrahedral, why is the bond angle in water less than that of ammonia?, The smaller size of oxygen atoms in H 2 O compared to nitrogen atoms in NH 3 leads to stronger repulsion between lone pairs of electrons, causing a smaller bond angle in water., Water molecules have a higher electronegativity than ammonia molecules, which results in stronger electron-electron repulsion and a smaller bond angle., The oxygen-hydrogen bond in H 2 O is weaker than the nitrogen-hydrogen bond in NH 3 , leading to a greater distortion of the bond angle in water., The presence of two lone pairs of electrons on the oxygen atom in H 2 O results in greater electron-electron repulsion and a smaller bond angle compared to ammonia.
