In argument, "over half of all automobiles built by the company since 1970 are still on the road today." is trying to play with Simple number percentage flaw.
Here is my line of reasoning for option "B", Please correct me, if, something is wrong in that.
B)- The number of automobiles built by Deluxe each year has not increased sharply since 1970.
You can understand this option by thinking in this way-"Let's say that number of vehicle build were increased. In 1970s they were building 100 vehicle, in 1980s 200 and so on and now in 2020s, suddenly, they are making 10+ million. In this case, even if all vehicle were scraped in same year they were purchased before 2020s, still there are 10+ million vehicle that are still on the road that is far more than half of total build till date. Hence, we can not conclude this is due to durability."
Hope this helps!!!!

I could not get the logic behind this que why manufacturing less cars shows they are more reliable and durable?

The Argument:
Claim: Deluxe cars are durable Evidence: 50%+ of cars built since 1970 still on road (vs. 33% for others)
The Hidden Flaw:
The stat says "since 1970" - but WHEN were most cars built?
Imagine This:
Simple Example:
"Half of all students I've taught since 2000 still remember my lessons!"
If you taught 10 students from 2000-2020 and 1000 students in 2024, that stat is meaningless - most are recent students!
But if you taught evenly across 24 years, then students from 2000, 2005, 2010 still remember - that's impressive!
What B Does:
B says production has NOT increased sharply.
This means → Cars spread evenly over time → Old cars still running → Genuine durability proven ✓

The Hidden Flaw:
The stat says "since 1970" - but WHEN were most cars built?
Imagine This:
| Scenario | What Happened | 50% Still Running Means... |
|---|---|---|
| Production spiked recently | 90% of cars built after 2015 | Of course they run - they're NEW! |
| Production stayed stable | Cars spread evenly 1970-2024 | Old cars from 70s/80s still running = REAL durability |
