A
nobelium (No) and lawrencium (Lr)
B
berkelium (Bk) and californium (Cf)
C
actinium (Ac) and thorium (Th)
Correct answer
D
neptunium (Np) and plutonium (Pu)

Solution

N p

and

P u

show maximum number of oxidation states starting from

+ 3

to

+ 7

all oxidation states.

Hence, the correct answer is option: 'D'.
