Answer:

The correct option is the A

Step-by-step explanation:

Like oxygen is more electronegative than hydrogen, it attracts electrons stronger than hydrogen. Therefore the two covalent bonds are polar.

The option b is incorrect because if oxygen and hydrogen had similar electronegativities, they would form no-polar bonds.

The option c is incorrect because oxygen is more electronegative than hydrogen (you can check that in a periodic table).

The options d and e are incorrect because the molecular size or hydrophilic don't influence the type bond.
