Final Answer :
C
Explanation :
Trisomy is a condition in which a person inherits an extra copy of a chromosome. This is commonly seen in conditions such as Down syndrome (trisomy 21) and Edwards syndrome (trisomy 18). Monosomy is the opposite condition, where a person is missing a chromosome, while disjunction, inversion, and duplication describe different types of chromosomal abnormalities.
