  • B
    any two parents differing in single pair of contrasting characters.
  • C
    two pure parents differing in single pair of similar characters.
  • D
    a parent and its offspring showing the same genotypes.

Solution

A monohybrid cross is defined as a genetic cross between two pure (homozygous) parents that differ in a single pair of contrasting characters.

For example, a cross between a pure tall plant ($TT$) and a pure dwarf plant ($tt$) is a monohybrid cross.

Answer: two pure parents differing in single pair of contrasting characters.

Hence, the correct answer is option: 'A'.
