A is correct. CO2 is non polar. although the CO bond is polar, the whole molecule is non polar since it is linear resulting to cancellation of dipole moments.
B is wrong. PCl3 is polar. The lone pair in P is strong thus it has a dipole.
C is also correct. Acetic acid is polar.
D is correct. The geometry of PCl5 is trigonal bipyramidal resulting to cancellation of dipole even if P-Cl bonds are slightly polar due to electronegativity difference bet P and Cl.

a and c are correct for sure and I think b and d are correct too. CO2 is non-polar because it is symmetrical
