Given:

The length of diameter is 44 cm.

Concept used:

If an angle subtended by a chord on the circumference of a circle is 90 degrees, then the chord is the circle's diameter. 

The diameter is the double of radius.

Calculation:

Using, If an angle subtended by a chord on the circumference of a circle is 90 degrees, then the chord is the circle's diameter. 

Length of chord MN = 44 cm

∴ Option 1 is the correct answer.
