Explanation:

Spiral galaxies are classified into normal spiral and barred spiral. A barred spiral galaxy has a bar - shaped structure through its center from which the spiral arms extend. Football - shaped is more characteristic of elliptical galaxies. Irregularly shaped is for irregular galaxies. Arms starting close to the center is a general feature of spiral galaxies but not specific to the second type (barred spiral).

Answer:

has a bar through the middle from which arms extend
