In the following sentence, choose the alternative that best improves the bracketed part. (What is worser) is that there is practically no room for improved relations as long as Mr Gupta keeps the issue floating.

Introduction / Context:
This question focuses on the correct comparative form of the adjective "bad". The sentence reads, "(What is worser) is that there is practically no room for improved relations as long as Mr Gupta keeps the issue floating." The phrase in brackets contains a non standard form. We must select the grammatically correct expression that correctly introduces a worse aspect of the situation.

Given Data / Assumptions:

• The sentence is pointing out an even more serious aspect of an already bad situation.
• The bracketed phrase is "What is worser".
• The options include:
  • What is worsen
  • What is worse
  • What is worsing
  • No improvement
• We assume the intended standard phrase is "What is worse".

Concept / Approach:
We recall the correct comparative and superlative forms of "bad":

• bad – worse – worst

The word "worser" is non standard and not used in modern formal English. Similarly, "worsen" is a verb meaning "to become worse", and "worsing" is not a standard form. We therefore check which option uses the correct comparative adjective in the right structure.

Step-by-Step Solution:
Step 1: Recognise that the sentence is introducing an additional and more serious problem, so it needs the comparative adjective "worse". Step 2: Option B, "What is worse", is the standard expression used to introduce an additional negative point. Step 3: Option A, "What is worsen", incorrectly uses the verb "worsen" in place of an adjective, which does not fit this structure. Step 4: Option C, "What is worsing", is not a valid English form at all and must be rejected. Step 5: "What is worser" in the original sentence is also incorrect, because "worser" is not accepted in standard modern English. Therefore, "No improvement" is wrong. Step 6: The only correct and idiomatic option is "What is worse".

Verification / Alternative check:
Insert the correct phrase into the sentence: What is worse is that there is practically no room for improved relations as long as Mr Gupta keeps the issue floating. This sounds natural and matches common written and spoken usage. It clearly indicates that the point given in the clause is even more serious than an earlier issue being discussed. Any of the other forms would either be ungrammatical or non standard.

Why Other Options Are Wrong:

• What is worsen: Uses the verb "worsen" wrongly in a slot where an adjective is required.
• What is worsing: Not a valid word in English.
• No improvement: Rejects the need to correct "worser", which is incorrect in standard English.

Common Pitfalls:
Students sometimes confuse archaic or dialectal forms with standard ones. "Worser" may occasionally appear in older literature, but it is not acceptable in modern exam level writing. Another pitfall is to mix up the verb "worsen" with the adjective "worse". Remember that "worse" compares two negative states, while "worsen" describes a change in state, as in "The situation may worsen".

Final Answer:
The correct improved expression is What is worse, so the correct option is "What is worse".
