Explanation / Answer

Here our task is to make conclusion about the Testing of means, the method we will use is p-value method,

In this method we will reject H0 if p-value <0.05

Otherwise accept H0

In the above problem we can see the p-value is 0.3992

So p-value >0.05

Hence according to the decision we will accept H0.

So the option B is correct, the both mean are same.
