Correct answer: D. Thymus glandथायमस ग्रंथि
Explanation
Hurlock divides developmental change into acquisition of new features and loss of old features. Permanent teeth and the primary and secondary sex characteristics are newly acquired during growth. The thymus gland, in contrast, shrinks and atrophies after puberty, so it belongs to the loss of old features, not acquisition.हरलॉक विकासात्मक परिवर्तन को नवीन लक्षणों के अधिग्रहण तथा पुराने लक्षणों के ह्रास में बाँटते हैं। स्थायी दाँत तथा प्राथमिक एवं द्वितीयक लैंगिक विशेषताएँ वृद्धि के दौरान नई अर्जित होती हैं। इसके विपरीत थायमस ग्रंथि किशोरावस्था के बाद सिकुड़कर क्षीण हो जाती है, अतः यह पुराने लक्षणों के ह्रास में आती है, अधिग्रहण में नहीं।More Child Development & Pedagogy questions
