Analyzing the "Black Cats Only in Northern America" Claim

The statement "Black cats can only be found in countries of Northern America" is false. The phrase to underline for the true/false analysis is "Northern America" (option c).

Reasoning: Black cats are a coat-color variant of the domestic cat (Felis catus), which is globally distributed. They are found on every continent except Antarctica, including Europe, Asia, Africa, South America, and Australia. The claim incorrectly restricts their range to Northern America (typically defined as Canada, U.S., Mexico, and sometimes Central America/Caribbean).
