Fill in the blank in the sentence given below by choosing the correct option out of those that follow.
I speak ______ truth. I am not afraid of it.

Correct option is A

The correct option to fill in the blank is (a) the.
Detailed Explanation (English):
• “Truth” is an abstract noun, and in many fixed expressions we use “the” with it.
• “Speak the truth” is a standard, idiomatic structure meaning to speak honestly.
• The phrase also points to truth in a definite sense (the truth = what is true), so “the” fits best.
Correct sentence: I speak the truth. I am not afraid of it.
Grammatical Rule Used (English):
• Definite article “the” is used with some abstract nouns in fixed/idiomatic usage (e.g., the truth, the past, the future).
• “the” is used when we mean something definite/specific in context.
Grammatical Rule Used (Hindi):
• “the” का प्रयोग तब होता है जब किसी वस्तु/भाव को निश्चित (definite) रूप में या fixed expression में कहा जाता है।
• “the truth” एक स्थापित प्रयोग है, जिसका अर्थ “सच” (निश्चित रूप से) होता है।
Why other options are incorrect:
• (b) Some: would mean “some amount of truth” (कुछ सच) — संदर्भ में उपयुक्त नहीं
• (c) A: “a truth” सामान्यतः किसी एक तथ्य/सत्य के लिए आता है, यहाँ नहीं
• (d) An: vowel sound से पहले आता है, और “truth” के साथ नहीं आता
