I think Cohesion is the correct answer.

Mercury is highly cohesive so it has a very high force of attraction between similar molecules. So mercury doesn't wet the glass.

In the case of Mercury, if we put a tube inside the beaker full of mercury then the level of mercury in the tube will fall and the tube doesn't get wet because cohesive force is more than adhesive force. This property is called adhesion.

According to me, Cohesive force is the correct answer. Surface tension is also a reason because of cohesive force b/w surface molecules of mercury.

The fluid property due to which mercury does not wet the glass is *cohesion*.
Mercury has strong cohesive forces between its molecules, which leads to high surface tension and prevents it from spreading out and wetting the glass surface.
