Final answer:
The property of neutron stars that does NOT state a property is that neutron stars contain strong gravitational fields but weak magnetic fields.
Step-by-step explanation:
The sentence that does NOT state a property of neutron stars is option C) Neutron stars contain strong gravitational fields but weak magnetic fields.
Neutron stars actually have
strong magnetic fields
. They are highly magnetized due to the conservation of angular momentum during their formation. These strong magnetic fields lead to the emission of
relatively narrow beams of light and other radiation
, which is stated in option B).
