The eligibility to contest in Legislative Assembly elections in India is determined by the Constitution of India and the relevant laws of each state. To understand why the correct answer is option 'D' (2015), we need to consider the age requirement and the duration of residency.

1. Age requirement:
To be eligible to contest in Legislative Assembly elections in most states, a person must be at least 25 years old. The person in question was born on 01-01-1990, so we need to determine when they would turn 25.

- On 01-01-2015, the person would have turned 25 years old. Therefore, they would have met the age requirement to be eligible for the Legislative Assembly elections.

2. Duration of residency:
In addition to the age requirement, a person must also fulfill the residency requirement. This typically involves being a resident of the state for a minimum period of time, which varies from state to state.

Since the question does not mention any specific state, we cannot determine the exact residency requirement. However, it is safe to assume that the person would have had sufficient time to meet the residency requirement by 2015, considering that they were born to Indian parents.

Therefore, based on the age requirement and assuming the person meets the residency requirement, the correct answer is option 'D' (2015).

It is important to note that the eligibility criteria for Legislative Assembly elections may vary slightly from state to state. However, the age requirement of 25 years is generally consistent across states. To determine the exact eligibility of a person in a specific state, it is necessary to refer to the laws and regulations of that particular state.
