Show answer & explanation
Correct answer: A
Answer: The effort estimation for organic software in basic COCOMO is E = 2.4 × (KLOC)^1.05 person-months.
Explanation: Basic COCOMO estimates effort using the power-law formula E = a × (KLOC)^b, where KLOC is thousands of delivered source lines of code. Different project modes use different a and b values.
Organic mode parameters: a = 2.4, b = 1.05.
Therefore: E = 2.4 × (KLOC)^1.05 person-months.
Quick note: For context, other basic COCOMO modes use different coefficients (for example, semi-detached commonly uses a ≈ 3.0, b ≈ 1.12; embedded uses a ≈ 3.6, b ≈ 1.20), which is why the specific a and b above identify the organic case.
