When all the strings on a guitar are stretched to the same tension, the speed of a wave along the most massive bass string will be B. slower.
<h3>How to explain the information?</h3>
It should be noted that the speed of the wave is inversely proportional to the square root of the linear density.
Therefore, when all the strings on a guitar are stretched to the same tension, the speed of a wave along the most massive bass string will be slower.
In conclusion, the correct option is B.

Answer:
v/U=0.79
Explanation:
Given u=
Now for the given flow to be possible it should satisfy continuity equation
Applying values in this equation we have
Thus we have
Hence proved
For maximum value of v/U put y =
Thus solving we get using the given values
v/U=0.79
