Answer:
B
Step-by-step explanation:
Using the method of cross- multiplication
= 
⇒ ad = bc
If ad ≠ bc then equation is not true
A
= 
, then
10 × 6 = 12 × 5 = 60 ← equation is true
B
= 
, then
69 × 10 = 690 and 100 × 6 = 600
690 ≠ 600 ← equation not true
C
= 
, then
10 × 100 = 5 × 200 = 1000 ← equation is true
D
= 
, then
12 × 2 = 4 × 6 = 24 ← equation is true
