Hint: In 2050, the world population is expected to grow by more than 25 percent from the existing population in 2020. According to estimates from 1960, the world population was about 3 billion. It is predicted that the population of 25 countries will at least double between 2020 and 2050. A population growth of 150 percent or more is expected for Angola, Benin, and Niger.

In demographics, the total number of people actually residing is the world population and as of March 2020 it was projected to have reached 7,800,000,000 people. For the world population, it took more than 2 million years of human prehistory and history to reach 1 billion, and then 200 more years to reach 7 billion.

Following the Great Famine of 1315-1317 and the end of the Black Death in 1350, when it was near 370 million, the world population continued to rise. Between 1955 and 1975, the highest rate of global population growth, with rises of over 1.8 percent each year, peaked at 2.1 percent between 1965 and 1970. Between 2010 and 2015 and 2015, the growth rate dropped to 1.2 percent.

However, the global population is still increasing and is projected to reach about 10 billion in 2050 and more than 11 billion in 2100. The global population, however, is still growing and is estimated to hit approximately 10 billion by 2050 and over 11 billion by 2100.

Now let us look into the given options
-In 1974, the population reached 4 billion. Option A is therefore an incorrect choice.
-By 2050, the population is expected to hit 10 billion. Thus, Option B is also inaccurate.
-According to 2020 estimates, the total world population is 7.8 billion. Since 6 billion is similar to 7.8, the correct response is Option C.
-In the year 180, the world population had crossed 1 billion. Thus, Option D is also not the correct answer.

Therefore, the correct answer is option ‘C’.

Note:
-The world's population is currently increasing (2020) at a rate of about 1.05% per year (down from 1.08 percent in 2019, 1.10 percent in 2018, and 1.12 percent in 2017).
-It is projected that the global annual population growth is 81 million individuals per year.
-In its World Population Prospects series, the United Nations Population Division of the Department of Economic and Social Affairs calculates, updates, and publishes projections of the total population every two years.
