Correct Answer: $(AD + BE + CF) < (AB + BC + CA)$


Solution :
Here, $AB+AC>2AD$ ---------------(1)
$AB+BC>2BE$ -------------------(2)
$BC+AC>2CF$ -------------------(3)
By adding equation (1), (2), and (3), we get,
$2(AB+BC+AC)>2(AD+BE+CF)$
$⇒(AB+BC+AC)>(AD+BE+CF)$
Hence, the correct answer is $(AD + BE + CF) < (AB + BC + CA)$.
