C.

select data:BIKE.BIKEID

Answers
C.

select data:BIKE.BIKEID

D.

select data:BIKE:BIKEID

Answers
D.

select data:BIKE:BIKEID

Suggested answer: C

Explanation:

In Snowflake, when accessing elements within a JSON object stored in a variant column, the correct syntax involves using a colon (:) to navigate the JSON structure. The BIKEID attribute, which is a child of the BIKE root node in the JSON object, is accessed using data:BIKE.BIKEID. This syntax correctly references the path through the JSON object, utilizing the colon for JSON field access and dot notation to traverse the hierarchy within the variant structure.

Reference: Snowflake documentation on accessing semi-structured data, which outlines how to use the colon and dot notations for navigating JSON structures stored in variant columns.
