In which year was Einstein born?

Correct answer: 1879

The governing biographical fact is that Albert Einstein was born on 14 March 1879 in Ulm, Germany. Thus option B, 1879, is the correct answer. The calculation is not an arithmetic operation; it is a recall question requiring the birth year stated in the lesson. The nearby alternatives 1875 and 1885 may seem believable because they are close to the correct date, while 1890 is later and cannot be Einstein’s birth year. A reliable memory pair is “1879 in Ulm.” Keeping the exact year together with the city helps distinguish this fact from later dates connected with his education, employment and scientific career.
