answer:
our sun will never become a neutron star. 
explanation:
- neutron stars are born from suns that are 10-20 times the size of ours. 
- in 5 billion years our sun will become a red giant and then eventually a cold white dwarf which is similar to a neutron star, just much larger and much less dense.

The answer is A. Dew point is the temperature at which air will turn into water vapor, a state between gas and liquid. If the temperature is further cooled down to lower than the dew point, water will condense, in other words, the gas state of air will turn into liquid state of water.
