what is verb in correct option d. is it "is" or "claims"

Vikram, I think the verb in option D is "claims".

yeah, 'claims' is verb but i am unable to articulate in grammar terms what is "IS". functionally, "is" describes the state of claim i.e. if "is" is replace by "was" then state of claim changes. i think "it claims" modifes "what" and "is" is part of the question.

what it claims is the world's smallest network digital camcorder ?

what is verb in correct option d. is it "is" or "claims"

The electronics company has unveiled what it claims is the world's smallest network digital camcorder, which is as long as a handheld computer and weighs less than 11 ounces.

Clause 1 - The electronics company has unveiled
Clause 2 - what, it claims, is the world's smallest network digital camcorder (xx)
Clause 3 - which is as long as a handheld computer and weighs less than 11 ounces (yy)

The electronics company has unveiled xx, yy

IMO main verb is HAS UNVEILED;
CLAIMS = is part of the modifier
IS = main verb of the relative clause (world's smallest network digital camcorder IS this)

COMMA is generally not used in some small length modifiers that confuse us sometimes - if there were comma before and after IT CLAIMS we can easily understand

D

"Which" is referring to camcorder and there is no ambiguity with "it".
