In a K-map, cells are ordered 00, 01, 11, 10 because:

  1. it makes the map smaller
  2. it is the binary counting order
  3. it removes the need for groups
  4. neighbouring cells must differ in only one variable (Gray code)
Answer

D) neighbouring cells must differ in only one variable (Gray code)

Gray-code order makes adjacent cells differ by one bit so that grouping removes a variable. SLO CS-11-A-01
