a tetrahedra
b bent
c linear
d nonpolar
e polar

Explanation:

1. For the shape of the water molecule ($\ce{H2O}$) from the Lewis dot structure: The central oxygen has two bonding pairs (with H) and two lone pairs. The electron - pair geometry is tetrahedral (due to 4 electron groups: 2 bonds, 2 lone pairs), but the molecular geometry (shape) is bent (because the lone pairs repel the bonding pairs, giving a bent shape, not linear. Tetrahedral is electron - pair geometry, but the molecular shape is bent, so B (bent) is correct, A (tetrahedra - note: the question might have a typo, but if we consider molecular shape, bent is for molecular, tetrahedral for electron - pair; however, if the options are about the diagram's molecular shape, bent is correct. Also, for polarity: The $\ce{O - H}$ bonds are polar, and the bent shape means the dipole moments don't cancel, so the molecule is polar (E is correct), not nonpolar (D is wrong). Linear (C) is wrong as water is bent. So the two correct terms are B (bent) and E (polar).

Answer:

B. bent, E. polar
