we need to weaken it
(A) Most of the IT support calls related to software issues occurred during business hours when the volume of software use was highest.
(not Relevant at what time they called)(B) The affordable update subscriptions were offered equally to all business sectors, including both small and large companies.
not Relevant, as calls from small business mentioned(C) IT support companies noted that calls about software integration issues were more frequent during major software release cycles.
(it actually strengthens the answer, as those calls were not about the update but about the software integration, but integration after update so updates are going there)
(D) Throughout the 2010s, regulatory requirements for data security in software were more strictly enforced than policies on software update compliance.
(not Relevant)
(E) The number of small businesses in the region increased significantly during the 2010s.
(if the number increase, then may be calls also increased in the calls)
so true weakner
