The correct option is B. The newest crust on earth is located at the actual site of the floor spreading and as new crusts are formed they replace it. Thus, the older the crust the farther it is from the mid ocean ridge. 
Sea floor spreading is a geological process in which tectonic plates splits apart from one another. It occurs at divergent plate boundaries.

Answer:
The tRNA is released from the E site of the ribosome and the elongation process finishes while the termination process starts.
Explanation:
When the translocation process is finished the tRNA that is in the E site  of the ribosome is released and the A site of the ribosome reads a stop codon in the mRNA in order to finish the elongation process and start with the termination process.  In the termination process  a termination factor joins the stop codon, the ribosomal subunits split apart, the protein and the tRNA dissociate from one another and the tARN is not in the P site of the ribosome anymore.
