Explanation / Answer
datafile=read.csv("C://Users/CHANDRA/Desktop/AllCountries.csv", TRUE, sep = ",") #Reading data
print ("Total number countries: ")
print ( nrow(datafile))
#Changing NA values to zeros
datafile$Developed[which(is.na(datafile$Developed))] <- 0
datafile$Internet[which(is.na(datafile$Internet))] <- 0
#print Max developed country with largest internet access
print(datafile[ datafile$Developed == max(datafile$Developed, na.rm=TRUE) & datafile$Internet == max(datafile$Internet, na.rm=TRUE) ,])
print(" ")
#Printing countries with maximum and minimum land area
print(datafile[ datafile$LandArea == max(datafile$LandArea, na.rm=TRUE),])
print(datafile[ datafile$LandArea == min(datafile$LandArea, na.rm=TRUE),])
