The Titanic was considered as safe that it carried only 20 lifeboats.

Correct option is D

· Original Sentence: The Titanic was considered as safe that it carried only 20 lifeboats.
· Grammar Rule: When expressing a cause-effect relationship using a degree of comparison, the correct correlative construction is “so + adjective + that.”
· ❌ “as safe that” is incorrect — "as...that" is not a valid grammatical structure.
· ✅ The correct form is “so safe that”.
· Explanation: The adjective “safe” is used to express a degree that results in a consequence — it carried only 20 lifeboats because it was believed to be extremely safe. This requires the construction “so safe that...”
· Corrected Sentence: The Titanic was considered so safe that it carried only 20 lifeboats.
· Option Analysis:
· (a) No improvement – ❌ Incorrect due to wrong structure “as safe that.”
· (b) very safe that – ❌ “Very” is not used in correlative clauses with “that.”
· (c) so much safe that – ❌ Incorrect combination; “so much” is not used with adjectives like “safe.”
· (d) so safe that – ✅ Correct and idiomatic usage.
Therefore, the correct improvement is (d) so safe that.
