You would be in Pressure Group F.
Improved AnswerUsing which table and which depth? ... since 12 meters is not 42 feet and instead is 39.4 feet. Using PADI's RDP, you have a PG of D if using the metric table of 12 meters or the imperial table of 40 feet. If using 42 feet on the table version of the RDP, then the PG is F, but if using the wheel or the new electronic RDP, then the PG is E (as it rounds up to 45 feet).
With the U.S. Navy table (or a modification thereof such as NAUI's or SSI's version), then the PG is C at 12 m./40 ft.
The BS-AC' 88 table gives you a PG of C and the DCIEM table results in B.
If you're using PADI's Recreational Dive Planner, pressure group F. You would roung the depth to 50', and 24 minutes is already desgnated.

Depending on your diving organisation this may be different but please see below
These are assuming no decompression stops and that the 24 minutes is at an actual bottom time.
I'm afraid I don't have a copy of the BSAC tables with me otherwise I could calculate for BSAC too.

The pressure group for a diver that dived to a depth of 14m for 24 minutes is pressure group F.
Pressure group F.
The PG would be "K".
According to NAUI's dive tables: 25 Minutes 17 Meters for 23 minutes: Group E 30 Minutes at surface: Still Group E (Would need 55 minutes to go to D) 25 Minutes is your adjusted maximum dive time for up to 18 meters.
Pressure group F.

The no-decompression limit at 18 meters is 48 minutes and that will take you to pressure group S. This information can be found in any Table or wheel RDP (recreational diving planner) and it is basic. If you do not know how to use this table, you shouldn't really be diving. If you are in a course, then you will have a lot of time to practice. Dont forget to dive well within your no decompression limit. Live on the edge, Dive safe.
The deepest dive to the bottom of Atlantic ocean was 10,994 meters deep. It was done by Don Walsh in a submarine and the dive took 4 hours and 47 minutes.
the pressure is more than the human body is designed to cope with.
Of course it depends on the depth, but the maximum is 219 minutes at 10.5 meters.
The final pressure group you would be in is M.
The dolphin is capable of diving for up to 20 minutes at 300 meters, this is to be considered as maxima for a bottlenose dolphin, although in some experiments they have dived to about 500 meters. Usually, bottlenose dolphins will not dive very deep.
