Option 1 states that both statements are individually true, and statement II is the correct explanation for statement I. However, this is incorrect.

Statement I states that the Earth is shaped more like a tangerine. This is not entirely accurate. The Earth is actually an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. So, statement I is true to some extent.

Statement II states that the Earth spins faster at the poles. This is false. The Earth actually spins at a constant rate, completing one rotation in approximately 24 hours. The speed of rotation is the same at all points on the Earth`s surface. Therefore, statement II is false.

Since statement II is false, it cannot be the correct explanation for statement I. Therefore, option 1 is incorrect.

Option 2 states that both statements are individually true, but statement II is not the correct explanation for statement I. This is the correct answer.

Option 3 states that statement I is true, but statement II is false. This is the correct answer.

Option 4 states that statement I is false, but statement II is true. This is incorrect.

In conclusion, option 3 is the correct answer as statement I is true, but
