Question

We start by restating the core operation: the SQL statement uses LIKE '%to%', which means we are searching for the substring 'to' appearing anywhere within the value of the name column.
Option 1: all names with "to," such as Roberto and Tommy. This aligns with the rule that any name containing the letters t followed by o, in that order, somewhere inside the string should be matched. Roberto ends with 'to' and Tommy begins with 'to', so both contain the substring 'to', making this option a correct description of what the query would return in a dataset that includes those entries.
Option 2: all names without "to," such as Samantha or Kathryn. This is incorrect because the LIKE '%to%' predicate excludes names that do not contain the substring 'to' at all; thus, Samantha and Kathryn would not satisfy the condition.
Option 3: all names starting with "to," such as Tommy or Tony. This would require the pattern 'to%' (beginning with 'to'), not '%to%', so this statement describes a different filter condition than the one used in the query. Therefore, this is not what the query returns.
Option 4: all names ending with "to," such as Roberto. While it is true that Roberto ends with 'to', the wildcard pattern '%to%' covers any position of 'to' within the string, including ends, middles, or starts. Saying it only ends with 'to' is too narrow and therefore not an exact description of the general behavior of the predicate.
In summary, the essence of the LIKE '%to%' predicate is that any name containing the substring 'to' anywhere in the string will be included, which makes the first option the most representative statement among the choices, while the others mischaracterize the pattern either by restricting position or by asserting the opposite of what the condition actually does.
