A. physical combat or escape are the situations that the human body readies itself for, and it is as effective as a sophisticated security system is
B. the human body readies itself for a physical combat or escape situation, and is as effective as a sophisticated security system
C. the human body readies itself for a physical combat or escape situation, and is as effective as a sophisticated security system is
D. the human body readies itself for a physical combat or escape situation, and is as effective than a sophisticated security system is
E. situations of physical combat or escape are what the human body readies itself for, and it is as effective as a sophisticated security system is
My Reasoning process:
-> A - doesn't seem right with sensing dangers modifying physical combat - Wrong
-> B looks good with the starting modifier (sensing danger, the human body.....) however, B violates the comparison using as. (Like compares nouns, As compares clauses).
->
C looks good till now-> D wrong comparison (as effective than a.....)
-> E - Wrong (modifier problem) sensing danger, situations
