In the absence of an adequacy decision pursuant to Article 45(3), or of appropriate safeguards pursuant to Article 46, including binding corporate rules, a transfer or a set of transfers of personal data to a third country or an international organisation shall take place only on one of the following conditions:
These conditions are individually sufficient and jointly necessary (https://hyp.is/e0RRFJCfEeqwuR_MillmPA/en.wikipedia.org/wiki/Necessity_and_sufficiency).
Each of the conditions listed is a sufficient (but, by itself, not necessary) condition for legal transfer (T) of personal data to a third country or an international organisation. In other words, if any of those conditions is true, then legal transfer is also true.
On the other hand, the list of conditions (C; let C be the disjunction of the conditions ag: a or b or c ...) are jointly necessary for legal transfer (T) to be true. That is:
 T cannot be true unless C (one of a or b or c ...) is true
 if C is false (there is not one of a or b or c ... that is true), then T is false
 T ⇒ C
 C ⇐ T
