Correct Option (A)
The passage explicitly states, "I can now give myself the certificate that a thoughtless word hardly ever escapes my tongue or pen. I do not recollect ever having had to regret anything in my speech or writing. I have thus been spared many a mishap and waste of time." This directly attributes the avoidance of mishaps to the author's careful and restrained use of words, ensuring that no thoughtless word is uttered or written.
Incorrect Options:
- Option (B) he is a man of immense patience: While the author's restraint might imply patience, the passage does not directly state or emphasize patience as the primary reason for being spared mishaps. The focus is on the economy of words and careful speech.
- Option (C) he believes that he is a spiritual person: The passage mentions "silence is part of the spiritual discipline of a votary of truth," but this is presented as a consequence or a related benefit of his shyness and word economy. The direct cause for avoiding mishaps is his disciplined speech and writing, not merely a belief in being spiritual.
- Option (D) he is a votary of truth: Being a votary of truth is mentioned in the context of spiritual discipline and the necessity of silence to overcome the natural human weakness of exaggerating or modifying truth. However, the immediate and direct reason provided for being spared mishaps is the absence of thoughtless words, which stems from his shyness and habit of restraining thoughts, rather than solely being a votary of truth.
