I'm sorry. "spelt" is a word, the past tense of "spell", and you used it correctly. "Spelled" is a better usage, though.

To identify the word that is spelled incorrectly in the given sentence, you can read through each word and compare it with the correct spellings.

In this case, the correct spellings are:

A. pitch
B. popular
C. conspicuously
D. ambidextrous

Based on this, the word that is spelled incorrectly in the sentence is "ambidectrous". The correct spelling is "ambidextrous" (meaning being able to use both hands equally well).
