Trying to differentiate between the three muscle tissues with small pictures
Without answering the problem for you, because you have not shown work yet to try to figure out which is which, let me tell you that you have three options.


Skeletal Muscle- striated, peripherally located nuclei, same thickness along length, non-branching 
Cardiac Muscle- striated, few centrally located nuclei, branches and anastamosis
Smooth Muscle- non-striated, centrally located single nucleus per cell, tapering ends


Now, hopefully, based on your pictures, which are indeed sufficient for you to figure out which is which, you can answer your own question. Good luck!
