When identifying the odd one out, look for the category each item belongs to. In this case, factors of production are being compared to the outcome (profit).
Let's analyze the options:
- Land, Labour, and Capital are all factors of production in economics. These are the inputs needed for the creation of goods and services.
- Profit is the result or outcome of using land, labour, and capital in production, rather than an input.
Thus, Profit is the odd one out.
Therefore, the correct answer is \( \boxed{3} \).
