Ensures minimal tracking error and high fidelity to the benchmark.

Suitable for highly liquid and straightforward indexes like the S & P/TSX Composite.

Sampling:

Used for large, complex indexes where holding all securities is impractical.

Selects a representative sample to approximate the index ' s performance.

Rules-Based and Synthetic ETFs:

Employ predefined rules or derivatives rather than physical securities.

Option D reflects the primary method of mirroring an index ' s performance through full replication, ensuring accuracy and minimal tracking error.
