Explanation

Parametric estimating is a recognized tool and technique for activity duration estimating (per the PMBOK Guide), using statistical relationships between historical data and variables to calculate duration - for example, multiplying the number of units by a known productivity rate.

Why the distractors are wrong:

• B. Monte Carlo analysis is a simulation technique used for risk analysis and schedule modeling, not a primary estimating method.
• C. Top-down estimating is an analogous (high-level) estimating approach applied at the project or phase level, not a formal PMBOK-named technique for activity duration specifically - it's a description of analogous estimating, not a distinct tool.
• D. Bottom-up estimating is a tool for activity cost estimating and work package effort estimation, not specifically classified under activity duration estimating in the PMBOK framework.

Memory tip: Think "Para-metric = Para-meter = Measure with a parameter." If you have a rate (hours/unit, cost/meter), you're using parametric estimating - it's data-driven and precise, making it the go-to duration estimating technique on the exam.
