Comprehensive and Detailed Explanation From Exact Extract:
Equality operators compare two values to determine if they are equal or not equal, returning a boolean result. According to foundational programming principles, common equality operators are == (equal to) and != (not equal to).
Option A: "-." This is incorrect. The subtraction operator (-) is an arithmetic operator, not an equality operator.
Option B: "==." This is correct. The equality operator (==) checks if two values are equal (e.g., 5 == 5 returns True).
Option C: "/." This is incorrect. The division operator (/) is an arithmetic operator, not an equality operator.
Option D: "not." This is incorrect. The not operator is a logical operator that negates a boolean value, not an equality operator.
Option E: "<=." This is incorrect. The less-than-or-equal-to operator (<=) is a relational (comparison) operator, not an equality operator.
Option F: "!=." This is correct. The not-equal-to operator (!=) checks if two values are not equal (e.g., 5 != 3 returns True).
