Diminishing marginal product occurs when additional units of input result in a smaller increase in output. This is reflected in all three scenarios: (i) when line A is rising but at a decreasing rate, indicating each additional unit of input adds less to output; (ii) when line B is rising, as it typically represents total output increasing at a decreasing rate; and (iii) when line C, often representing marginal product, is rising but eventually decreases, directly indicating diminishing marginal product.
