Options

  1. AX = b l a c k , M n O 2 , Y = B l u e , K 2 C r O 4 , Z = K M n O 4
  2. BX = g r e e n , C r 2 O 3 , Y = Y e l l o w , K 2 C r O 4 , Z = K 2 C r 2 O 7
  3. CX = b l a c k , M n O 2 , Y = g r e e n , K 2 M n O 4 , Z = K M n O 4
  4. DX = b l a c k ; B i 2 O 3 , Y = c o l o u r l e s s K B i O 2 , Z = K B i O 3

Correct answer

C. X = b l a c k , M n O 2 , Y = g r e e n , K 2 M n O 4 , Z = K M n O 4

Step-by-step solution

Here X = b l a c k , M n O 2 , Y = g r e e n , K 2 M n O 4 , Z = K M n O 4
