Juanita and Jose are in different lab groups in Mrs. Gonzalez's science class. In class, they were learning about conductors and performed the following experiment. Each group was given four different materials—a copper wire, a fabric ribbon, a plastic straw, and a strip of aluminum metal. They were also given a battery and a light bulb. Each group used the different materials to connect the battery to the light bulb. If the light bulb lit up when connected, the material was a conductor of electricity. If the light bulb did not light up, the material was a nonconductor. Juanita and Jose's results are shown below.

JUANITA'S DATA
Material Light Bulb Lit?
Copper yes
Fabric no
Plastic no
Aluminum yes

JOSE'S DATA
Material Light Bulb Lit?
Copper yes
Fabric no
Plastic no
Aluminum yes

Juanita concluded that copper and aluminum are conductors.
Jose concluded that fabric and plastic are nonconductors.
How do their conclusions compare?

A. Only Jose's conclusion is correct.

B. Neither Juanita nor Jose's conclusion is correct.

C. Both conclusions are correct.

D. Only Juanita's conclusion is correct.
