निम्नलिखित गद्यांश को पढ़कर प्रश्नों के सर्वाधिक उपयुक्त विकल्पों का चयन कीजिए।

मेरा जी पढ़ने में बिलकुल न लगता था। एक घंटा भी किताब लेकर बैठना पहाड़ था। मौका पाते ही हॉस्टल से निकलकर मैदान में आ जाता और कभी कंकरियाँ उछालता, कभी कागज़ की तितलियाँ 'उड़ाता' और कहीं कोई साथी मिल गया, तो पूछना ही कया। कभी चारदीवारी पर चढ़कर नीचे कूद रहें हैं। कभी फाटक पर सवार, उसे आगे-पीछे लाते हुए मोटरकार का आनंद उठा रहे हैं, लेकिन कमरे में आते ही भाई साहब का वह रुद्र-रूप देखकर प्राण सूख जाते। उनका पहला सवाल यह होता- “कहाँ थे'? हमेशा यही सवाल, इसी ध्वनि में हमेंशा पूछा जाता था और इसका जबाब मेरे पास केवल मौन था। न जाने मेरे मुँह से यह बात क्यों न निकलती कि ज़रा बाहर खेल रहा था। मेरा मौन कह देता था कि मुझे अपना अपराध स्वीकार है और भाई साहब के लिए उसके सिवा और कोई इलाज न था कि स्नेह और रोष से मिले हए शब्दों में मेरा सत्कार करें।
