Which WHERE clause is SARGable and most likely to use an index on created_at?

Problem Statement

Explanation

SARGable predicates let the engine search the index without transforming the column. Range predicates on the raw column preserve index use. Wrapping the column in a function forces a scan in many engines because the index on the base value cannot be used directly.
