The head of a phospholipid can be described as a-polar and hydrophobic b-hydrophobic with a negative charge c-polar and hydrophilic d-nonpolar and hydrophilic

C-polar and hydrophilic

Explanation:

Phospholipids are the amphipathic molecules and have both polar and non-polar parts in their structure. The phospholipid head is a polar and hydrophilic part which makes the outer part of the bilayer in the cell membrane. The phospholipid tails are non-polar and hydrophobic and are buried in the core of the bilayer to stay away from water.
