Find mismatch pair from the following:
Cardiac muscle- heart
Skeletal muscle- striated
Smooth muscle- voluntary muscle
Smooth muscle- non-striated muscle
Option 3 is the mismatched pair : Smooth muscle - voluntary muscle
The matching pair should be : Smooth muscle - involuntary muscle
Smooth muscles are not under voluntary control, meaning we cannot consciously control their contractions. They are found in the walls of internal organs and blood vessels and are responsible for involuntary movements, such as digestion and regulation of blood flow. Hence, the correct answer is option 3.
