General English

Since 'She writes a letter' is in the simple present tense, its passive form must use the present tense of the verb 'to be' ('is') plus the past participle ('written'). Option A is incorrect because 'was written' shifts the sentence into the past tense. Option D is incorrect as it uses the continuous aspect.

The word 'ephemeral' means lasting for a very short time, which makes 'permanent' its correct antonym as it denotes lasting indefinitely. Option D is incorrect because 'temporary' is a synonym, not an antonym, of ephemeral. Similarly, 'brief' is also a synonym.
