Which of these has higher priority? writes, reads

Answer: Option A

In MySQL, writes typically have higher priority than reads.
When the database system faces contention between write operations (such as INSERT, UPDATE, DELETE) and read operations (such as SELECT), the write operations are generally given higher priority to ensure data consistency and integrity.
Option B, reads, is incorrect because writes usually take precedence over reads in MySQL.
Option C, same priority, is incorrect because writes typically have higher priority than reads.
Option D, machine dependent, is incorrect because the priority between writes and reads is not determined by the machine's characteristics; rather, it is a design principle in database systems like MySQL to prioritize writes for data consistency.
