Final answer:
The latest date among the options provided is D. Feb. 4, 1971, as it is the furthest along in the year compared to the others listed.
Step-by-step explanation:
To determine which of the given dates is the latest date, you should compare the year, month, and day in that order. January 1st of 1971 is after January 1st of 1970, and January 2nd is a day later than January 1st. However, both February 3rd and February 4th are after January 2nd. Since all dates are from the same year of 1971, you only need to look at the month and the day. February is the second month while January is the first, which makes any date in February later than any date in January. Among the February dates given, February 4th is later than February 3rd. Therefore, the latest date listed is D. Feb. 4, 1971.
