Task: Class Definition Understanding (ontology: Legal/LKIF_Core_Ontology)

Which of the following definitions best describes 'Application Date'?

A. The period during which a normative fragment may be either operative or inoperative, by explicit provision of the document itself. The document is said to be in a period of operation, or enforceability or efficacy, when it may or must be applied or enforced.
B. The date when the competent authorities finalise the document by affixing their signatures to it (e.g. promulgation by the president, signature by the queen etc.) This is the date shown on the document itself: it is an objective element and clearly identifyable.
C. The date when the normative document is published in the official journal designated as the source for making all such documents public and legal.
D. The date when a modification is applied to the destination legislative document. The date can be instantaneous, in the future or in the past. Normally this date coincides with the date of efficacy of the text in which the modification takes place.
