Let's analyze what the SQL pattern LIKE '%to%' means in a WHERE clause.

Option 1: 'all names starting with "to," such as Tommy or Tony' would require the pattern 'to%' to match names that begin with 'to'. Since the actual pattern uses '%to%', this option is too restrictive and misses names that contain 'to' later in the string.

Option 2: 'all names ending with "to," such as Roberto' would require the pattern '%to' to match names that finish with 'to'. The given pattern '%to%' requires 'to' to appear somewhere in the string, not just at the end, so this option is incomplete.

Option 3: 'all names with "to," such as Roberto and Tommy' aligns precisely with LIKE '%to%'. This pattern matches any name that contains the sequence 'to' anywhere inside it, whether at the start, middle, or end; examples include 'Roberto' (contains 'to') and 'Tommy' (contains 'to').

Option 4: 'all names without "to," such as Samantha or Kathryn' would require the opposite condition, typically using NOT LIKE '%to%'. This contradicts the given pattern and would select names that do not contain 'to', which is not what the query specifies.

In summary, the only option that faithfully represents the effect of LIKE '%to%' is the one describing names that contain the substring 'to' somewhere in the name, exemplified by Roberto and Tommy.
