FYI: I'm not 100% positive, but I'm pretty sure these are correct for the most part. Sorry I couldn't be more help!
The correct statement is: (2) Sister chromatids are genetically identical.
Sister chromatids are the copies of a single chromosome. These are therefore genetically identical. The sister chromatids are joined together at the region called centromere with the help of certain proteins. The chromatids are formed during the S phase of the interphase due to a process called duplication.
Chromosome is the compact form of DNA. It consists of the genetic material and certain proteins called histone proteins. The main role of chromosome can be seen during cell division. This is because the division of genetic material takes place in the chromosomal form.

Answer - D. (The genetic code)
The genetic code is the nucleotide base sequence on DNA (with which information is encoded within genetic material). The nucleotide base sequence<span> codes for a sequence of amino acids, which are in turn used by living cells as the basic building blocks of proteins.</span>
During bag-mask ventilation, giving a breath just until you see the chest rise is recommended to minimize the risk of gastric inflation. The compression-to-ventilation ratio for 1-rescuer adult CPR is 30:2<span>. The compression-to-ventilation (or breaths) ratio for 2-rescuer child/infant CPR is </span>15:2<span>.</span>
