C Correct answer
Explanation

Boundary value analysis tests at the edges of input domains and immediately beyond. For valid range 1900-2004, test just below (1899), at lower bound (1900), at upper bound (2004), and just above (2005). Options A and B miss the lower boundary test below, while D includes unnecessary interior values.
