In an IPv6 address, two or more consecutive groups of 0s can be compressed using...

IPv6 text representation permits zero compression to make long addresses easier to read and write. One or more consecutive 16-bit groups containing only zeros can be replaced by a double colon, subject to the rule that the double-colon compression is used only once in a single IPv6 address; otherwise the number of omitted groups would be ambiguous. In the address 2001:DBFF:130F:0:0:0:0:130B, four consecutive zero groups appear between 130F and 130B. Replacing that run with :: produces 2001:DBFF:130F::130B, which expands back unambiguously to the original eight groups. Leading zeros within an individual 16-bit group can also be omitted, but that is a separate abbreviation rule. The example in the question follows valid IPv6 notation and does not alter the numeric address. Consequently, the statement that the address can be compressed in the manner shown is TRUE. The correct answer is A. The compression changes only the written representation of the IPv6 address; it does not change the underlying 128-bit address value itself in any way.
