As velocities are tangent, the value of both Particle A and Particle B would be same for that point O (Intersecting point)
a = v / t
Here, v = 7, t = 6
So, a = 7/6
a = 1.17
As the graph is decreasing, value of acceleration would be negative.
So, a = -1.17 m/s²
In short, Your Answer would be Option C
Hope this helps!

Explanation:
Hello!
Let's solve this!
To know if the work is positive or negative we have to know the following:
The work is positive when the gas performs (expansion)
The work is negative when done outside on the gas (compression)
In this case the work is done by the gas, so it is positive.
The correct answer is option a. 400J
