Consider how the two WHERE clauses filter rows in SQL. 
Option 1 uses explicit comparison: credit_limit >= 100 AND credit_limit <= 10000. This means any row with credit_limit 100 or more, and 10000 or less, will be included.
Option 2 uses the BETWEEN operator: credit_limit BETWEEN 100 and 10000. BETWEEN is defined to be inclusive of both the lower and upper bounds, so it includes values equal to 100 and equal to 10000 as well as everything in between.
Because both expressions define the same inclusive range for numeric credit_limit values, they will return the same set of rows for all typical numeric data (assuming credit_limit is a numeric type and there are no unusual NULL handling quirks).
However, it’s worth noting a couple of subtle points: first, if credit_limit were NULL, both predicates evaluate to UNKNOWN and would exclude those rows in a WHERE clause; both forms behave the same in that case. second, if you were dealing with non-numeric types or attempting to leverage different collation or type conversion specifics, behavior could differ, but for a straightforward numeric range, the results coincide.
In summary, for numeric credits in standard SQL, the two statements are equivalent and yield the same results. Therefore, the statement is True.
