Answer : 3. "specialties"
Explanation :

Explanation: The sentence talks about understanding one's qualities, skills, and uniqueness. "Specialties" is the most appropriate word choice here as it refers to a person's particular areas of expertise or unique attributes.

"Calamities" refers to disasters or events causing distress, which doesn't fit the context of the sentence.

"Punctualities" refers to being on time, which is not relevant to the sentence's context.

"Fecundities" refers to fertility or the ability to produce offspring, which is unrelated to the message of the sentence.
