A Correct answer
Explanation

A decision table with n conditions can create 2^n possible combinations of condition outcomes. Each combination becomes a rule (column) in the table. For example, 3 conditions yield 8 rules, 4 conditions yield 16 rules. This exponential growth makes decision tables complex for many conditions.
