A sample of marble has deformed brittlely during a laboratory experiment.If we wish our next sample of marble to deform plastically rather than brittlely,we should conduct the next experiment at
A)lower temperature and lower confining pressure.
B)lower temperature and higher confining pressure.
C)higher temperature and lower confining pressure.
D)higher temperature and higher confining pressure.
