In a ribosome there are 3 tRNA sites (P, A and E).
The P site, also called the peptidyl site, binds to the tRNA holding the growing polypeptide chain of amino acids. THIS IS YOUR ANSWER!...P or peptidyl
The A site (acceptor site) binds the aminoacyl tRNA which brings the new amino acid that will be added to the polypeptide chain.
The E site (exit site) serves as the exit and is where the tRNA that has now lost its amino acid lets go of the ribosome.

<u>ANSWER:</u>
The correct option is B- Qualitative.

When the growth of corn has to be recorded, the quality of the corn grown in different soils needs to be recorded. Qualitative methods are best used to classify quality of anything.
Qualitative data basically is non-numerical data which in the case of corns can be the length of the corn plant, the sweetness of the corn kernel or the hardness or softness of the corn. This data cannot be recorded using numerical values and so other methods of data recording cannot be used.
