3 answers are correct. Hard

Show answer

Answer

  • A Missing for the missing age
  • B Type for "thirty"
  • D Range for "−3"

Explanation

The three single-value constraints fit exactly: range checks whether a value lies in the permitted range (−3 lies outside), type checks the data type (a string instead of an integer) and missing checks for missing values and attributes.
