Option A is the correct syntax for accessing a specific field in a data record using the dataReader object. The square brackets should contain either the column name as a string or the column index as an integer, and in this case, we are looking for the third field, so dataReader["lastName"] is the correct syntax. Option B is incorrect because it would return the value in the fourth column (since the index starts at zero). Option C and D are both incorrect because they attempt to access the lastName property from either the dataReader object or the get() function, which aren't applicable in this scenario.
