"Observable plant changes due to disease (spots, wilting, discoloration)" → a) Symptom
"Pathogen spread between hosts (insects, water, tools)" → b) Transmission
"Living organism (fungi, bacteria, viruses) causing plant disease" → c) Pathogen
"Pathogen enters & multiplies within plant tissue" → d) Infection
