To solve this problem, we need to use the formula for the conversion of units of pressure, which is:

1 atm = 29.92 in Hg

We can use this formula to convert the altimeter reading in Hg to atm:

19.00 in Hg x (1 atm / 29.92 in Hg) = 0.635 atm

Now, we need to consider the fact that the atmospheric pressure decreases with altitude. At an elevation of 12,000 feet (or 3,657.6 meters), the atmospheric pressure is about 0.635 atm (according to the standard atmosphere model). Therefore, the answer is:

Answer: C
