Question

which is the best way to complete the text?

studies suggest that meditation has many health benefits, __________ cardiovascular health, decreased cortisol (a hormone related to stress levels), and lower blood pressure.

such as the following,
improved

such as, improved

such as improved

such as: improved

Explanation:

The phrase "such as" is used to introduce examples without a comma or colon immediately after it. The correct structure is "such as [example]", and the example here needs the adjective "improved" to match the parallel structure of the listed benefits (decreased, lower). The other options have incorrect punctuation after "such as" or unnecessary extra text.

Answer:

such as improved
