In first molecule we have symmetric structure so net pull by green atoms to electrons will be balnced.
In second molecule it is 2D molecule in 2 axis and all 3 atoms are same ie have same electronegativity and hence net electronegative pull eill be balanced.
In fourth molecule it is symmetric in 3D. Four atoms in a plane will balance the net pull between them and 2 aroms i.e. top and bottom atoms will balance pull between them.
Only third molecule, as we can see 4 atoms in a plane will balance each other's pull but there is no atom on axis to compensae pull of atom on top. This will result net pull towards top by top atoms. And hence this molecule will be polar.

In a covalent bond between two atoms, the more electronegative atom will attract more electron density toward itself, producing a polar bond. The more electronegative element will carry a partial negative charge, whereas the less electronegative element will carry a partial positive charge. The direction of the bond dipole is always toward the more electronegative element. This is often indicated by an arrow, as shown in the figure. The magnitude of the bond polarity can be estimated by using the...

Use the table of electronegativity to identity polar bonds in the molecules. Indicate any polar bonds with appropriate arrows (and if there is no dipole moment, leave the target blank), and identify the molecule as polar or nonpolar.

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
