Sentence Correction

32. A year advantage in a new computer product or process being introduced can give a company a significant edge on its competitors.
a...
b. Introducing a new computer product or process by a year earlier
c. A year's advantage to introduce a new computer product or process
d. To introduce a new computer product or process by a year earlier
e. Being a year ahead in introducing a new computer product or process

IMO B. But OA is D. Plz explain.

I'm not sure..The given sentence and the options all look bad.

B looks better than D.
Can someone plz. explain this OA.........

C is also looking good to me.

Whats wrong with C??

Also
I think with year we use an and not a

I will finish this is an year.
I will finish this is a year.

To me first one looks better, please share your suggestions

IMO C.
Though I agree with Stop...An year is correct , not a year...

Coz if 1st alphabet of word sounds a vowel, then we put 'an'
eg... an hour ago...h is silent ..so 'an'

but all the choices here use A year..So C seems to be the best.

moreover if u read ...C...A year's advantage...can give...edge sounds appropriate.

you are incorrect, year is not preceded by an.

year is A year not AN year.

IMO D

B and E would be more sound if they immediately modify company
C looks unclear to me...and am concerned about the possesive form of year....year's advantage ? advantage is owned by the year or company ?

please explain between B and D.

please~

this question is debatable. I guess this is from SC 1000 list.

IMO, here both B and D are valid options.

We shouldn't worry too much about this question. We can move on to next question.

thank you. i was so worried because i couldn't get it right.

not to worries then~

Just read this question on a different forum.

Can anyone please explain why do you think option B is wrong?
