Explanation

The correct answer is B - selection of a top-performing portfolio to represent the firm's strategy.

Why this is correct:

The Global Investment Performance Standards (GIPS) were created primarily to address the problem of survivorship bias and cherry-picking in performance reporting. Before GIPS, investment firms could:

1. Select only their best-performing portfolios to represent their investment strategy
2. Exclude poorly performing portfolios that were terminated or closed
3. Create misleading performance composites that didn't represent the firm's actual performance

Key GIPS requirements that address this issue:

• Composite construction: Firms must include all actual, fee-paying, discretionary portfolios in at least one composite
• No cherry-picking: Firms cannot select only top-performing portfolios to represent a strategy
• Full disclosure: Must include terminated portfolios in historical performance
• Fair representation: Composites must fairly represent the firm's investment strategies

Why the other options are incorrect:

A - GIPS actually enables comparison of comparable time periods by standardizing performance calculation and presentation methods across firms.

C - GIPS requires the presentation of performance history that includes terminated portfolios to prevent survivorship bias, not prevents it.

Additional context:

GIPS standards were developed by CFA Institute to provide investment firms with guidance on how to calculate and present their investment performance fairly and consistently, ensuring comparability across firms and preventing misleading performance claims.
