Can some explain to me the way 'introducing' is used in B. If it is a verb, how can it be parallel to 'have improved' ??? In case it is a present participle, how can it stand alongside 'while', which I understand is a subordinating conjuction that requires a full clause?
Apart from its usage as a conjunction with a finite verb, 'while' is also used along with participles. GMAT has accepted this usage also, as can be seen below. Therefore, one cannot omit a choice on this count. 1. The themes that Rita Dove explores in her poetry

B. is universal, encompassing much of the human condition, also occasionally it deals
C. are universal, they encompass much of the human condition and occasionally deals
D. are universal, encompassing much of the human condition
while occasionally dealingE. are universal, they encompass much of the human condition, also occasionally are dealing

The non-underline part uses while along with a participle3. Meteor showers and individual streaks of light that flash across the sky every night are generated when tiny flecks of celestial detritus, often no larger than grains of sand or of pebbles, burn up speeding through the atmosphere.
(A) grains of sand or of pebbles, burn up speeding
(B) grains of sand or pebbles, burn up
while speeding (C) grains of sand or pebbles, which burn up while speeding
(D) a grain of sand or pebble, which burns up as it speeds
