Correct Solution: Option A

Step-by-step Solution:

Answer: A — CDF


Reasoning

The three statements in this set are:

  • C: All falcons are birds.
  • D: All birds are yellow.
  • F: All falcons are yellow.

We can form a logical syllogism using the first two statements:

"All falcons are birds" + "All birds are yellow" ⇒ "All falcons are yellow"

The conclusion of this syllogism is the exact same as statement F. Therefore, statements C and D logically entail F, making CDF the most logically related set.

Other sets do not form a complete and valid chain of logic. For example, the set DEF is missing statement C, which is needed to establish the initial connection between falcons and birds.
