Shashank is writing a SQL query with tables ABC and $xYZ($from schema named 'schema'$).$ He wants to return only the records from ABC where there is not a corresponding record in XYZ $($as displayed in the Venn diagram below:

His query so far is the following:

select

abc.field$1,$

abc.field$2,$

abc.field$3$

from schema.xyz

join schema.abc on

abc.primarykey $=$ xyz$.$foreignkey;

Which of the following types of joins should he specify in the query above where the blank $($blank$)$ is$?$
