Sentence Correction

The physical structure of the human eye enables it to sense light of wavelengths up to 0.0005 millimeters; infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye.

(A) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long to be registered by the eye

(B) however, the wavelength of infrared radiation—0.1 millimeters—is too long to be registered by the eye making it invisible

(C) infrared radiation, however, is invisible because its wavelength—0.1 millimeters—is too long for the eye to register it

(D) however, because the wavelength of infrared radiation is 0.1 millimeters, it is too long for the eye to register and thus invisible

(E) however, infrared radiation has a wavelength of 0.1 millimeters that is too long for the eye to register, thus making it invisible




choice c is ambigous however isnt choice a (solution) ambiguous also? in hcoice a we have a ITS but we dont know if it refers to the eye, structure, sense or light? I understand what the intention of the sentence is but overall the sentence solution is also ambiguous! Can someone explain the ambiguity!?

Is choice A the answer ?

A ends in a passive note, but still seems to okay when compared to C.
C has a pronoun error in 'it'.

I choose B

no particular reason
felt it explains in a simple, clear manner

can soemone explain?

The OA is (A)

There is nothing wrong with the original answer.

B - making it invisible modifies eye, rather than wavelength

C - It is ambiguous and lacks a clear referent

(all per the official guide)

Per the discussion, A is clear and grammatically correct.
