Step 1: Rural markets in India rely heavily on personal contact, word of mouth and trust built through direct interaction, because literacy levels and media reach are lower than in urban markets.
Step 2: A flashy or aggressive promotion can feel alien or pushy to a rural buyer, and pure repetition alone does not build the trust that a rural consumer needs before buying.
Step 3: Personal contact, through village-level demonstrations, local opinion leaders and one-to-one interaction, works best in building confidence in a rural setting, so the correct answer is Personal.
