Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. slightly.
- Slightly is the most appropriate as there is no other parameter for comparison, it here means that saliva has a little alkaline nature.
- If there had been a comparison, then slighter should've been used (comparative degree of slight)
- Slightest would've meant the smallest of amounts (superlative degree of slight)
- Slight is an adjective that can't be placed before another describing word, alkaline.
