Choose the correct sentence.

Correct answer: Quote this poem from memory.

✅ Explanation:

"from memory" is the correct and idiomatic phrase in English, meaning to recite something without reading or looking at it.

❌ "from the memory" is incorrect in this context — we don’t use “the” here.

❌ "from the heart" is acceptable in emotional or figurative contexts (e.g., "Speak from the heart"), but "Quote this poem from the heart" sounds unusual and imprecise.

❌ "from heart" is grammatically incorrect — it would need "the."

✅ So, the best and grammatically correct choice is:
"Quote this poem from memory."
