correct answer : a)
Explanation:
‘Demography’ is the study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations. Thus, ‘Demography’ is the correct one-word substitute. Option (a) is correct.
जनसंख्या के आँकड़ों (जैसे जन्म, मृत्यु, आय आदि) के सांख्यिकीय अध्ययन को ‘Demography’ (जनसांख्यिकी) कहा जाता है। अतः, रेखांकित भाग के लिए ‘Demography’ सही एक-शब्द विकल्प है। विकल्प (a) सही है।
