Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
YAML is a strict superset of JSON, allowing valid JSON to be parsed as YAML.
YAML is a superset of JSON, meaning any valid JSON document is technically also a valid YAML document, allowing direct mapping of data structures.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
JSON uses indentation for structure just like YAML.
Why it's wrong here
Incorrect. JSON uses structural punctuation like braces and brackets, ignoring whitespace indentation.
- ✗
JSON and YAML both strictly require curly braces for all data containers.
Why it's wrong here
Incorrect. YAML relies on indentation rather than curly braces for blocks.
- ✓
YAML is a strict superset of JSON, allowing valid JSON to be parsed as YAML.
Why this is correct
Correct. Because YAML includes JSON as a subset, JSON structures can be seamlessly interpreted by YAML parsers.
- ✗
YAML forces all numeric values to be encapsulated in strings.
Why it's wrong here
Incorrect. YAML supports native integer and float data types.
