Chiasmata, coz they didnt say two chromatids (most probably)
centromere
The chromatids of a chromosome are attached at a point called the centromere. The centromere is a region where the two chromatids are closely aligned and hold together until they separate during cell division.
Recall the Wobble-Base - here is a Wobble-Answer: This protein disk is called the di-Chromosome Centromere assembly disk [it brings - and temporarily Locks - the centromeres of the pair of Chromosomes together].
A chromosome is determined to be metacentric, acrocentric or telocentric by the location of its centromere. Centromeres are the point of attachment of two sister chromatids. Sister chromatids are formed during DNA replication prior to mitosis or meiosis. Chromosome Y by itself (when it is not replicating and there are no sister chromatids) is not acrocentric, as it wouldn't even have a centromere location.
The centromere is a region of a chromosome where two sister chromatids are joined together and serves as the attachment point for spindle fibers during cell division. Its primary role in mitosis is to ensure accurate segregation of chromosomes by facilitating the proper alignment and movement of chromatids to opposite poles of the dividing cell. This ensures that each daughter cell receives an identical set of chromosomes, maintaining genetic stability.
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.

The structure at the center of the chromosomes where sister chromatids are attached is called the centromere. It serves as a point of attachment for the spindle fibers during cell division and helps in the proper segregation of genetic material to daughter cells.

Centromere!
Recall the Wobble-Base - here is a Wobble-Answer: This protein disk is called the di-Chromosome Centromere assembly disk [it brings - and temporarily Locks - the centromeres of the pair of Chromosomes together].
The centromere is found in the middle of two sister chromatids. The sister chromatids are connected by the centromere in order to form a chromosome.
The copied sister chromatids remain attached to the centromere, which is a specialized region of the chromosome where the two chromatids are joined. This attachment is crucial for ensuring that each daughter cell receives one copy of each chromatid during cell division.
