Even without the mentioned chart, you call tell that answer C is correct: India and Namibia are less developed than Russia, because all other statements are false.
To support this claim, let us look at some of the measures commonly used to determine a country's level of development. These values are all from 2018.
- Gross National Product and Gross Domestic Product per capita. GNP in Russia was $10,230 per capita, against $2,020 for India and $5,220 for Namibia. GDP per capita was $11,289 in Russia, $2,010 in India and $5,931 in Namibia.
- Urbanization. The urban population as a percentage of the total population was 34% in India, 50% in Namibia, and 74% in Russia.
- Consumption per capita. Households' final consumption expenditure per capita was $1,189 in India, $4,876 in Namibia, and $6,203 in Russia.
- Literacy rate. The percentage of literate adults aged 15 and older was 100 in Russia, 74 in India and 88 in Namibia.
