  1. A1 only
  2. B2 only
  3. CBoth 1 and 2
  4. DNeither 1 nor 2Correct

Explanation

The correct answer is D because both statements are scientifically incorrect. Statement 1 is incorrect because the ELISA test, not FLISA, is the commonly known enzyme linked immunosorbent assay used for various medical screenings, but it is primarily used for detecting antibodies or antigens related to infections like HIV, rather than being the first and most basic test for cancer. Cancer detection typically starts with physical exams, imaging like X rays or CT scans, and biopsy. Statement 2 is incorrect because the distribution of Rh blood types is not equal. In reality, a vast majority of the global population, approximately 85 percent to 90 percent, is Rh positive. Only a small minority, around 10 percent to 15 percent, is Rh negative. Therefore, the 50 50 split mentioned in the statement is false.
