Correct option is A
The correct indirect/ direct speech is
(a).
Explanation of rules (Direct → Indirect for suggestions):
· Interrogative forms like
“Why don’t we…?” usually express a
suggestion rather than a genuine question.
· With the reporting verb
suggest, standard constructions are:
1.
suggest + gerund (-ing) → She suggested
checking with Mrinmay.
2.
suggest + that + clause (should + base verb) → She suggested that they (should) check with Mrinmay.
·
Suggest is
not followed by an infinitive (to check) or a bare verb (check) directly, and
not by
to + -ing.
· Pronouns/time markers adjust as needed; here, the infinitive/gerund choice is the key grammar point.
Structure:
·
Direct: “Why don’t we + V₁ … ?”
·
Indirect (gerund): S + suggested + V-ing …
·
Indirect (that-clause): S + suggested + that + S + (should) + V₁ …
Example:
Direct: “Why don’t we start early?”
Indirect: He suggested
starting early. / He suggested that they
should start early.
Why other options are incorrect:
·
(b) to checking — incorrect pattern; suggest does not take
to + -ing.
·
(c) check — bare verb after suggest is ungrammatical without
that and a subject.
·
(d) to check — suggest does not take the
to-infinitive (suggest to do ✗).
