Which of the following is NOT a popular surface for tennis courts?

a. Wood***
b. Grass
c. Clay
d. Hard Court

a is right

Oh, wood, definitely not a popular surface for tennis courts. I mean, can you imagine playing tennis on a giant chopping board? That would be quite the racket! Stick to the other options like grass, clay, or hard court, and leave the wood for chopping vegetables, not smashing serves!

The correct answer is a. Wood. Wood is NOT a popular surface for tennis courts.

To determine which of the options is NOT a popular surface for tennis courts, we need to understand what each surface is and its popularity in tennis. Let's go through each option:

a. Wood: Historically, wood was a popular surface for tennis courts. However, it is no longer widely used in professional tennis due to its maintenance requirements and limited availability.

b. Grass: Grass courts are known for their fast and low-bouncing surface. They are popular and commonly used in prestigious tournaments like Wimbledon. Grass courts require special care and are not as common as other surfaces.

c. Clay: Clay courts are made of crushed brick or shale and offer a slower playing surface. They are commonly used in professional tournaments like the French Open. Clay courts are quite popular in Europe and South America.

d. Hard Court: Hard courts are made of materials like asphalt or concrete and are the most common type of tennis courts globally. They provide a medium-paced surface and are used in many professional tournaments, including the Australian Open and the US Open.

Based on this information, we can see that **a. Wood** is the correct answer, as it is no longer a popular surface for tennis courts. The other options (b. Grass, c. Clay, and d. Hard Court) are all widely used and popular surfaces for tennis courts.
