Which are the essential prime implicants of the following Boolean function?

$f(a, b, c)= a' c+ ac'+b' c$

1. $a' c$ and $ac'$
2. $a' c$ and $b' c$
3. $a' c$ only.
4. $ac'$ and $bc'$

Using K map $f = ac' + a'c$

yes you are right, b'c is selective prime implicant.
+2

Just to see it visually ;)

Clearly $A\bar{C}$ and $\bar{A}C$ cover cells that are not covered by any others.
