Molecular orbital theory was developed mainly by
  • A
    Pauling
  • B
    Pauling and Slater
  • ✓
    Mulliken

Correct option: C.
Mulliken
c
Molecular orbital theory was developed in the years after valence bond theory had been established (1927), primarily through the efforts of Friedrich Hund, Robert Mulliken, John C. Slater, and John Lennard-Jones.

$MO$ theory was originally called the Hund-Mulliken theory.
