I must say that, beyond occasionally exposing me to laughter, my constitutional shyness has been of no disadvantage whatever. In fact I can see that, on the contrary, it has been all to my advantage. My hesitancy in speech, which was once an annoyance, is now a pleasure. Its greatest benefit has been that it has taught me the economy of words. I have naturally formed the habit of restraining my thoughts. And 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. Experience has taught me that silence is part of the spiritual discipline of a votary of truth. Proneness to exaggerate, to suppress or modify the truth, wittingly or unwittingly, is a natural weakness of man, and silence is necessary in order to surmount it. A man of few words will rarely be thoughtless in his speech; he will measure every word. We find so many people impatient to talk. There is no chairman of a meeting who is not pestered with notes for permission to speak. And whenever the permission is given the speaker generally exceeds the time- limit, asks for more time, and keeps on talking without permission. All this talking can hardly be said to be of any benefit to the world. It is so much waste of time. My shyness has been in reality my shield and buckler. It has allowed me to grow. It has helped me in my discernment of truth. For the author, silence is necessary in order to surmount

Explanation
The passage explicitly states: "Proneness to exaggerate, to suppress or modify the truth, wittingly or unwittingly, is a natural weakness of man, and silence is necessary in order to surmount it."
Option D) tendency to overstate, directly corresponds to "Proneness to exaggerate."
Let's look at the other options: A) constitutional shyness: The author considers his shyness an advantage, a "shield and buckler," not something to surmount. B) hesitancy in speech: The author states his hesitancy in speech is "now a pleasure" and taught him economy of words, not something to surmount. C) suppression of thoughts: The author mentions "restraining my thoughts" as a positive outcome that leads to avoiding "thoughtless word(s)," which is different from suppressing all thoughts or good thoughts. Silence helps prevent thoughtless speech, not surmount the suppression of thoughts.
Therefore, D is the correct answer as it directly reflects what the author states silence is necessary to overcome.
