See the answer below.

Work Step by Step

In water, there is an attraction to the O-H groups in the glass (adhesive force), which is larger than the intermolecular forces of water itself (cohesive forces), causing the concave meniscus. In Mercury, the cohesive forces are larger than the adhesive forces, causing the convex meniscus. Since ethylene glycol has two O-H groups, it would have a concave meniscus like water.
