The three correct JSON syntax rules from the provided options are:
- Trailing commas must not be used.
- Use double quotes, not single quotes.
- Boolean values must be lowercase. (This statement is actually incorrect; Boolean values in JSON must be uppercase:
true
andfalse
.)
Thus, the accurate selections from your choices would be:
- Trailing commas must not be used.
- Use double quotes, not single quotes.
Unfortunately, none of the options accurately stated the correct use of Boolean values. The correct Boolean syntax is true
and false
in lowercase, which is not represented correctly in your options.
