Early-acting stress sensors provide the initial signal for the stress response,  several possible examples of stress-sensing mechanisms that act early in the pathway have been identified. They include:

A) calcium channel (cyclic nucleotide-gated calcium channel) that senses changes in temperature

B) A kinase (SnRK1, a SNF1-related kinase 1) that senses energy depletion during stress

C) A plasma membrane histidine kinase (ATHK1) that senses osmotic stress

D) A leucine rich repeat receptor kinase (LRRK) protein (Srlk)

E) An endoplasmic reticulum transmembrane sensor inositol-requiring enzyme 1 (IRE1)

And activating several response after sensing these mechanisms;

i) activates hundreds of stress-response transcripts

ii) that functions as an upstream regulator of salinity responses in Arabidopsis

iii) that is required for acclimation to heat stress

iv) that is required for heat tolerance in plants

v) activates ABA-dependent and ABA-independent responses

Which of the following is the correct match the activating response with its sense mechanism;
