Question

$A=\{1,2,3,4\}$ and $B=\{a,b,c\}$. The relations from $A$ to $B$ is

• A. $\left\{\right(1,2),(1,3),(2,3),(2,4),(3,4),(3,1\left)\right\}$
• B. $\left\{\right(a,b),(a,c),(b,a),(b,c),(c,a\left)\right\}$
• C. $\left\{\right(1,a),(1,b\left)\right(1,c),(2,a),(2,b),(2,c),(3,a),(3,b),(3,c),(4,a),(4,b),(4,c\left)\right\}$
• D. $\left\{\right(a,1),(1,3),(b,2),(c,3),(b,3),(b,4\left)\right\}$

Answer 1

Answer: (C)

$\left\{\right(1,a),(1,b\left)\right(1,c),(2,a),(2,b),(2,c),(3,a),(3,b),(3,c),(4,a),(4,b),(4,c\left)\right\}$

$A=\{1,2,3,4\}$

$B=\{a,b,c\}$

Possible Relation $R:A\to B$

$=\left\{\right(1,a),(1,b\left)\right(1,c),(2,a),(2,b),(2,c),(3,a),(3,b),(3,c),(4,a),(4,b),(4,c\left)\right\}$

Option C contains Relation $R:A\to B$
