The national park covers 1.42 × 10^12 acres (1.42 billion acres).
The national forest covers 1.2 x 10% acres, which is 1.2 x 10^(-1) * 1.42 × 10^12 = 1.704 × 10^11 acres (170.4 million acres).
The total number of acres in the park and the forest combined is 1.42 × 10^12 + 1.704 × 10^11 = 1.59 × 10^12 acres (1.59 trillion acres).
Therefore, the correct answer is O 1.59 × 10^12.
