As per given by the question,

There are given that,


\angle AEF=38^(\circ)

Now,

According to the properties of the line,

The sum of the total angle on the line is equal to 180 degree and the opposite angle is same.

So,

There are ,


\angle AEF=38^(\circ)

So,

The opposite angle of angle AEF is,


\angle BEC=38^(\circ)

So, the amgle BEC is 38 degree.

Hence, the option C is correct,
