[tex]a\rightarrow b[/tex]
the expression or condition implies that, if the value is "a", then it corresponds with "b".
[tex]b\rightarrow c[/tex]
For the second condition, if "b", then it corresponds with "c".
Therefore, we can say that, "a" also corresponds with "c"
[tex]a\rightarrow c[/tex]
The answer is Choice C.
You can also interpret it as equality :
like, a=b, b=c, then a=c
