Consider the following statements A and B : Statement A : In Manali, houses…

Concept: Across India, traditional house design tracks local climate and terrain — hilly, snow-fed regions use wood/stone with sloping roofs so snow and rain slide off, while flood-prone river-plain regions raise houses on stilts to stay above rising water.

Application: Manali sits in the Himalayan belt of Himachal Pradesh, so its houses are indeed wood-built with slanting roofs — but they rest on solid stone-and-timber foundations, not on bamboo pillars. Raising a house on bamboo pillars is Assam's response to seasonal river floods, not Manali's response to snow, so Statement A wrongly imports that Assam feature into Manali and does not hold. Manali's own climate genuinely brings heavy monsoon rain in summer and heavy snowfall in winter, so Statement B holds.

• "A is incorrect, but B is correct" matches: the bamboo-pillar detail belongs to Assam's flood-adapted stilt houses, not Manali's wood-and-slanting-roof homes, so A does not hold; Manali's rain-and-snowfall pattern is real, so B holds.

• "Both A and B are correct" fails: it treats the bamboo-pillar detail as valid for Manali, but that detail describes Assam's flood-adapted houses — Himachal homes stand on stone-and-timber, not bamboo stilts.

• "Both A and B are incorrect" fails: it doubts Manali's rain-and-snowfall pattern, but the region genuinely gets heavy monsoon rain and winter snow.

• "A is correct, but B is incorrect" fails on both counts: it treats the bamboo-pillar detail (an Assam feature) as valid for Manali and doubts the region's real rain-and-snowfall pattern.

Cross-check: this same combination is also the option marked in CTET's official August 2023 Paper 1 answer key, and it is the only offered combination consistent with both facts.
