A radioactive nuclide ${}^{A}_{Z}X$ undergoes radioactive decay inside a cloud chamber. The radiations emitted are subjected to a magnetic field and the resulting tracks are as shown in the figure. What are the atomic number and the mass number of the remaining nuclide ?

Cloud chamber with a magnetic field acting out of the paper; a radioactive nuclide emits a track that curves

	Atomic Number	Mass Number
	$Z-2$	$A-4$
	$Z+1$	$A-4$
	$Z+1$	$A$
	$Z-1$	$A-4$
