Step-by-Step Solution

Solution:

Step 1: Identify subproblems for integer break
Break down the integer n into smaller integers and find max product for each.
Step 2: Use DP to store intermediate results
Store max product for integers from 1 to n to avoid recomputation.
Final Answer:
Option D -> Option D
Quick Check:
DP fits optimization over overlapping subproblems [OK]

Quick Trick: Integer break is a classic DP optimization problem [OK]
