Based on the data thomson collected in his experiments using cathode rays, the concept of atomic structure was modified. what statement about the atomic structure was validated by his cathode ray experiments?

I encountered this same question, these were the choices given.
1). In the atom, the particles of the cathode rays are embedded in a diffuse cloud of positive charge. 
2).Cathode rays have mass. 
3).Matter contains positive and negative charge. 
4).The positive component of matter is also particulate in nature. 
5).Particles of the cathode rays are fundamental to all matter. 
6).An atom is divisible. 
7).Particles of the cathode rays are negatively charge.

There are more than one correct statement. These statements are:

2).Cathode rays have mass.
3).Matter contains positive and negative charge. 
5).Particles of the cathode rays are fundamental to all matter. 6).An atom is divisible. 

The correct choice is c
