Dear Fluke
were "only" not there
then B would have been a straight away answer (why would we need St A)
Actually, just the reverse would be correct. Please see the attached picture.

Morning Session Only = Grey Color = M
Both (Morning Session+Afternoon) = Orange Color = M&A
Afternoon Session Only = Yellow Color = A
Q: If M+M&A+A=128
M=?
St1:
M&A=96
Not Sufficient.
St2:
M&A+A=112
Now, we know M&A+A+M=128
M&A+A=112
So, M=16(Morning Session only)
Sufficient.
Ans: "B"
******************************************************************************
Now, if the question were: How many people attended morning session, we are asked to find M+M&A
St1:
M&A=96
Not Sufficient.
St2:
M&A+A=112
Now, we can't find "M&A+M" using this information and the stem.
Not Sufficient.
Together:
We can find "A" and eventually "M&A+M".
Sufficient.
Ans: "C"
