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 top 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
please dicuss the subject of infinitive .Who is performing the action of registering

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


((Too long to -is the correct usage))

(B) however, the wavelength of infrared radiation--0.1 millimeters--is top long to be registered by the eye
making it invisible (( Here Making it refers to wavelength or radiation, infrared or eye??? ))
(C) infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long for the eye
to register it

((Lengthy))


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


(( it Refers to wavelength , infra red should be visible not wavelength))
(E) however, infrared radiation has a wavelength of 0.1 millimeters that is too long for the eye to register,

((that refers to 0.1 millimeters))

(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,


Who is doing the "registering " action in " to register " in C, D and E
