The Type B trees produces 120 pears.

<h3>What is meant by percentage?</h3>

A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.

<h3>How many pears did the Type B trees produce?</h3>
  1. Type A trees produced 20 percent more pears than Type B trees did
  2. Type A trees produced 144 pears.

Let us consider, Type B produced 100% pears.

So, Type A will produce 120%of B, that is 144

144 = 120/100 * B

simplifying the above equation, we get

144 * 100 = 120B

B = 14400/120

B = 120

The value of B = 120.

Hence, the Type B trees produces 120 pears

Therefore, the correct answer is option B) 120.
