Correct answer: C. 1898

  • A. 1896
  • B. 1897
  • C. 1898

Explanation

Giovanni Battista Grassi's work helped establish that malaria parasites develop in and are transmitted by mosquitoes, with the key discovery dated to 1898. Students may choose 1897 because important malaria transmission observations occurred around that period, but the standard date for Grassi's life-cycle discovery is 1898.
