Acceleration is a measure of how fast the velocity of a particle/object is changing at a point. Therefore, acceleration can be measured by finding the slope of the velocity of the particle at a certain point.
Since we are given the graph of velocity, we have to find the slope of the particle at point B. In the given graph, the slope of the velocity of the particle at point B is zero. Therefore, the acceleration of the particle at point B is 0.
Hope this helps!

B. solid
Explanation:
The solid state of matter is made up of particles that build repeating patterns. Solid is one of the four physical states of matter.
- Matter is described as anything that has weight and occupies space.
- The four states of matter are solid, liquid, gas and plasma.
- Solid particles are known to be closely packed and held together by very strong attractive forces.
- Solid like sodium chloride are said to be crystalline because they have crystals.
- Crystals are ordered atomic structures formed by repeating units of the fundamental molecular units.
- The repeating patterns of the crystals builds to form a solid.
- Other states of matter do not posses the repeating crystalline structure of solids.
