Option 1 -> CBT is not about herbal alternatives; it's a talking therapy focused on thought processes.
Option 2 -> CBT is described as a talking therapy that addresses thought processes to help cope with challenges, making this the primary purpose.
Option 3 -> CBT is therapy-based, not medication prescription; it's used as a first-line treatment before pharmacological options.
Option 4 -> CBT is a "talking therapy" that addresses mental patterns, not physical exercise programs.
Hence, Option 2 -> The passage explicitly states that CBT "helps individuals cope with challenges in life by addressing their thought processes" and is recommended as a first-line treatment for sleep problems in individuals with underlying anxiety or depression before resorting to medications -> correct
