This question is related to Entity$-$Relationship Modeling. A weak entity set in an E$-$R diagram is an entity set that:

Group of answer choices

Must have an identifying relationship with the owner entity

Must have a primary key

May have a partial key

Must have a one$-$to$-$one relationship with the owner entity

Must be exactly one on the owner entity $($non weak$)$ end of the identifying relationship

Can only have identifying relationships $($cannot have normal relationships$)$

None of these
