​Study the given pattern carefully and select the number that can replace the question mark (?) in it.

​

Logic: The multiple of the stars digits is equal to the sum of squares digits. 

Figure 1: 5 $$\times$$6 = 30 $$\rightarrow$$​12 + 18 = 30.

Figure 2: 6 $$\times$$8 = 48 $$\rightarrow$$​20 + 28 = 48.

Figure 3: 7$$\times$$2 = 14 $$\rightarrow$$?  + 6 = 14

? = 14 - 6 

? = 8

Thus, the correct option is (a) 8
