Both companies A and B provide customers with 24-hour hotline consultation services for customers who have problems with their company's digital products. Dialing the hotline charges a corresponding call fee, so generally, consumers only have difficulties when using digital products. Company A will receive 5 times more hotline calls than Company B. This shows that Company A's digital products must be more complex and difficult to use than Company B. If the following are true, the above conclusions are most supported:. ['Company B has twice as many consumers of digital products as Company A.', 'Company A has five times more consumers of digital products than Company B.', 'Company B receives twice as many complaints about digital product quality issues as Company A.', 'Company A receives five times more complaints about digital product quality issues than Company B.']
