Which three data types can a SOQL query return? Choose 3 answers

The most common return type for a SOQL query is a List of sObject records, for example, List<Account> or List<Contact>.

While Long is a valid Apex data type, SOQL aggregate functions like COUNT() return Integer if the count fits, or use COUNT(fieldname) which returns Integer. A direct SOQL query doesn't explicitly return a Long type for standard data.

For aggregate functions like COUNT(), a SOQL query can return an Integer value representing the count of records.

Each row returned by a SOQL query, representing a record, is of the sObject type, or a specific child type like Account or Contact. A query returns a List of these sObject instances.

While Double is a valid Apex data type for decimals, SOQL aggregate functions for sums (SUM()) or averages (AVG()) typically return Decimal type, not Double.
