Finding the Correct Spelling

The question asks us to identify the word that is spelled correctly from the four given options. Spelling rules in English can be tricky, and sometimes words look similar but only one follows the standard convention.

Let's look at the provided options:

• Option 1: coalesce
• Option 2: coalecse
• Option 3: coelesce
• Option 4: coalase

Now, let's analyze each option to determine which one is correctly spelled.

• coalesce: This word means to come together and form one mass or whole. For example, different groups might coalesce into a single organization. This is the widely accepted and correct spelling of the word.
• coalecse: This spelling reverses the order of the letters 'c' and 's' at the end of the word. This is not the correct spelling.
• coelesce: This spelling uses an 'e' instead of an 'a' after the 'o'. The correct spelling uses 'oa'. This is an incorrect spelling.
• coalase: This spelling omits the second 'c' and uses an 'a' instead of an 'e' before the 's'. This significantly deviates from the correct spelling and is incorrect.

Comparing all the options with the standard English spelling, we find that only "coalesce" is spelled correctly.

Therefore, the correctly spelt word is coalesce.
