Which option is least scientific in India's location?

Answer and explanation

Correct answer: India's standard time changes due to colour of sea

The direct answer is C: India’s standard time changes due to the colour of the sea. This is the least scientific statement because sea colour has no role in deciding time. Standard time is fixed by longitude, especially a selected standard meridian. Step by step, places at different longitudes have different local solar times because Earth rotates from west to east. India uses 82°30′E as its Standard Meridian, and Indian Standard Time is based on it. Option A is scientifically correct: differences in longitude cause differences in local time. Option B is correct because north–south latitudinal extent influences the angle of sunlight and contributes to climatic variety. Option C is wrong and therefore the answer: the colour of the sea cannot alter a clock or standard meridian. Option D is correct because India’s peninsular shape and surrounding seas support maritime contact. Exam cue: time—longitude; climate—latitude; sea colour—no scientific role.
