Directions : In the following question, a sentence with two highlighted…

Concept: Two grammar points govern this item. First, the NOUN “delay” takes the preposition “in” before a gerund — the fixed pattern is “delay in doing something,” not “delay on doing” or the bare “delay doing.” Second, the verb tense must match the time frame: an event whose result still matters “once it becomes available” calls for the present perfect (has done) or the simple past (did), while the past perfect (had done) needs a second, later past event to sit behind — which this sentence does not supply.

Applying it: Fix the two highlighted phrases in the original sentence:

1. Preposition: “delay on releasing” → “delay in releasing.” The noun “delay” demands “in” + gerund.

2. Tense: “had left fans disappointed” → either “left fans disappointed” (simple past) or “has left fans disappointed” (present perfect). Both connect naturally to the present-time clause “once it becomes available”; the past perfect has no later past event to anchor it.

Checking each variant:

• Variant (i) — “delay in releasing / left fans disappointed yet eager”: correct preposition + valid simple past. Acceptable.

• Variant (ii) — “delay in releasing / has left fans disappointed yet eager”: correct preposition + valid present perfect tying the disappointment to the present. Acceptable.

• Variant (iii) — “delay releasing / had left fans disappointed yet eager”: the noun “delay” here drops its required “in,” and the past perfect lacks an anchoring later past event. Not acceptable.

Result: Variants (i) and (ii) are both grammatically and contextually correct; variant (iii) is not. The correct answer is “Both (i) and (ii).”
