B

Step 1: Understand the concept of meniscus in liquids. The meniscus is the curve in the surface of a liquid in response to its container due to cohesive and adhesive forces.
Step 2: Identify the type of meniscus based on the angle of contact. A concave meniscus forms when the adhesive forces are stronger than the cohesive forces, which typically occurs in polar liquids like water. Hence, the resulting shape is parabolic.
Step 3: Analyze the options:

• Option A: Plane - this does not accurately describe a liquid meniscus.
• Option B: Parabolic - correct for liquids like water with a concave meniscus.
• Option C: Semi-spherical - incorrect, as it describes a stronger cohesive force.
• Option D: Cylindrical - incorrect, as it implies uniformity not present in a standard liquid meniscus.

Therefore, the answer is B.
