The correct Active/Passive form of the given sentence is:

☀ People consider him a good Boss.

Explanation for other options:

☀ People considered him as a good Boss. This option is in the active voice and changes the tense of the verb from present to past, but it still correctly represents the action of people considering him a good Boss.

☀ People have considered him as a good Boss. This option is also in the active voice and represents the action of people considering him a good Boss using the present perfect tense.

☀ Peoples had been considered him as a good Boss. This option is not grammatically correct. The subject should be "People," not "Peoples." Additionally, the use of "had been considered" is not appropriate in this context.
