Urgent native opinion needed! Paragraph Question

If engineers waited for the development of scientific knowledge to use and organize into technological achievements, ours would be a very different world from what we know. In engineering, it is not so much science as it is ingenuity that is applied to solve problems and satisfy needs and wants. If this were not so, the steam engine would never have been invented in the absence of thermodynamics. The Wright Brothers would not have flown since they had no aerodynamics textbooks. The astronauts would never have landed on the Moon nor the rovers on Mars without firm geological knowledge of their surfaces. Rather than following scientific theories and discoveries, engineering leads them. Operating steam engines prompted the development of thermodynamics, actual powered flight drove aerodynamics, and Moon and Mars missions brought back samples and sent back data that led to increased scientific knowledge about those extraterrestrial bodies.

One point made in the passage is that inventions ----.
A) relate more to physics than to chemistry
B) are made in response to the recognition of a need
C) are almost always based on some degree of scientific knowledge
D) are valued more than new scientific theories
E) do not usually relate to our ordinary everyday life

What is/are your opinion(s) about the option "B" and "D"? My choice is "D".

Any effort'll be much appreciated! Thanks in advance:)
