Goode’s Homolosine is an interrupted projection: it is a composite, equal‑area map that deliberately “cuts” the globe into lobes to reduce distortion.

Relevant concepts:
- Interrupted projections introduce deliberate breaks (interruptions) along chosen meridians or oceans so landmasses are shown with less shape and area distortion.  
- The Goode Homolosine specifically is a hybrid (sinusoidal + Mollweide) equal‑area projection that is “interrupted” into several lobes.  
- Planar (azimuthal) projections map the globe onto a single plane; they produce a continuous circular or oval map without the multiple separated lobes typical of interrupted projections.

Step‑by‑step reasoning:
1. Visual inspection of the pictured map shows multiple separated lobes (panels) with gaps or seams between them rather than one continuous sheet.  
2. Those seams align with oceanic regions and break the map into several teardrop/oval lobes so continents appear in less distorted shapes—this is the hallmark of an interrupted projection.  
3. The Goode Homolosine’s design (combining sinusoidal near the equator with Mollweide for higher latitudes) is implemented by interrupting meridians; that combination is a known definition of the Goode Homolosine.  
4. A planar (azimuthal) projection would show the Earth projected onto one single plane surface (often circular) with no repeated lobes or deliberate separations; the pictured map does not match that pattern.

Why the correct answer is correct:
- The multiple lobes and intentional seams are exactly what “interrupted projection” means, and the Goode Homolosine is the canonical example of such a projection.

Why the other option is incorrect:
- “Planar projection” implies a single continuous projection onto a plane (azimuthal), which does not produce the separated lobes and interruptions seen here.

Conclusion: The Goode’s homolosine map is an interrupted projection. This matches the provided correct answer: interrupted projection.
